Fix installation of 32bit libraries after r288074.
FILES is not used when LIBRARIES_ONLY is set, which is used to build and install the lib32 sysroot. All of the csu files do quality as "libraries" for this case so just undefine LIBRARIES_ONLY.
This is still better than the previous realinstall handling as it does not hook into META_MODE properly.

Replace realinstall: and META_MODE staging hacks with FILES mechanism.
This partially reverts r270170 for lib/csu/i386 while retaining the change for using bsd.lib.mk.
These FILES groups could go into lib/csu/Makefile.inc but I've kept them in the Makefiles for clarity.

Use bsd.lib.mk here as all other csu Makefiles do.
This effectively reverts r124752.
There's no reason this should be different. It resulted in needing NO_PIE in the original opt-out NO_PIE commit as this was not using the proper framework.

Revert r267233 for now. PIE support needs to be reworked.
1. 50+% of NO_PIE use is fixed by adding -fPIC to INTERNALLIB and other build-only utility libraries. 2. Another 40% is fixed by generating _pic.a variants of various libraries. 3. Some of the NO_PIE use is a bit absurd as it is disabling PIE (and ASLR) where it never would work anyhow, such as csu or loader. This suggests there may be better ways of adding support to the tree. Many of these cases can be fixed such that -fPIE will work but there is really no reason to have it in those cases. 4. Some of the uses are working around hacks done to some Makefiles that are really building libraries but have been using bsd.prog.mk because the code is cleaner. Had they been using bsd.lib.mk then NO_PIE would not have been needed.
We likely do want to enable PIE by default (opt-out) for non-tree consumers (such as ports). For in-tree though we probably want to only enable PIE (opt-in) for common attack targets such as remote service daemons and setuid utilities. This is also a great performance compromise since ASLR is expected to reduce performance. As such it does not make sense to enable it in all utilities such as ls(1) that have little benefit to having it enabled.

In preparation for ASLR [1] support add WITH_PIE to support building with -fPIE.
This is currently an opt-in build flag. Once ASLR support is ready and stable it should changed to opt-out and be enabled by default along with ASLR.
Each application Makefile uses opt-out to ensure that ASLR will be enabled by default in new directories when the system is compiled with PIE/ASLR. [2]
Mark known build failures as NO_PIE for now.
The only known runtime failure was rtld.

After r217375, some startup objects under lib/csu are built in a special way: first they are compiled to assembly, then some sed'ing is done on the assembly, and lastly the assembly is compiled to an object file.
This last step is done using ${CC}, and not ${AS}, because when the compiler is clang, it outputs directives that are too advanced for our old gas. So we use clang's integrated assembler instead. (When the compiler is gcc, it just calls gas, and nothing is different, except one extra fork.)
However, in the .s to .o rules in lib/csu/$ARCH/Makefile, I still passed CFLAGS to the compiler, instead of ACFLAGS, which are specifically for compiling .s files.
In case you are using '-g' for debug info anywhere in your CFLAGS, it causes the .s files to already contain debug information in the assembly itself. In the next step, the .s files are also compiled using '-g', and if the compiler is clang, it complains: "error: input can't have .file dwarf directives when -g is used to generate dwarf debug info for assembly code".
Fix this by using ${ACFLAGS} for compiling the .s files instead.

Stop calling _init/_fini methods from crt1 for dynamic binaries. Do call preinit, init and fini arrays methods from crt1 for static binaries.
Mark new crt1 with FreeBSD-specific ELF note.
Move some common crt1 code into new MI file ignore_init.c, to reduce duplication. Also, conservatively adjust nearby sources for style.

Apply a workaround for a binutils issue with the .note.ABI-tag section generated from lib/csu/common/crtbrand.c (which ultimately ends up in executables and shared libraries, via crt1.o, gcrt1.o or Scrt1.o).
For all arches except sparc, gcc emits the section directive for the abitag struct in crtbrand.c with a PROGBITS type. However, newer versions of binutils (after 2.16.90) require the section to be of NOTE type, to guarantee that the .note.ABI-tag section correctly ends up in the first page of the final executable.
Unfortunately, there is no clean way to tell gcc to use another section type, so crtbrand.c (or the C files that include it) must be compiled in multiple steps:
- Compile the .c file to a .s file. - Edit the .s file to change the 'progbits' type to 'note', for the section directive that defines the .note.ABI-tag section. - Compile the .s file to an object file.
These steps are done in the invididual Makefiles for each applicable arch.

Do not create *.gmon files for PIE executables on i386.
Scrt1_c.o was accidentally compiled with -DGCRT (profiling), like gcrt1_c.o. This problem is i386-specific, the other architectures are OK.
If you have problems with PIE executables such as samba and cups leaving behind gmon files, rebuild them after installing this change.

Properly support -fPIE by linking PIE binaries with specially-built Scrt1.o instead of crt1.o, since the later is built as non-PIC.

Removed "-fkeep-inline-functions" from CFLAGS, since it now has no effect except to generate spurious warnings about a system header <sys/param.h> having some inline functions (the bswap family). This backs out the main part of rev.1.5 (which was the only part left). The problem fixed by rev.1.5 of the Makefile went away in rev.1.5 of ../common/crtbegin.c when the references to do_ctors() and do_dtors() in the latter were moved from inline asm to C code.
This leaves the problem that implementation details cause warnings.

Do not use __progname directly (except in [gs]etprogname(3)). Also, make an internal _getprogname() that is used only inside libc. For libc, getprogname(3) is a weak symbol in case a function of the same name is defined in userland.

* Bring back the guts of crt{i,n}.S. This allows C++ exceptions to work when using the egcs and gcc-devel ports, along with GCC built from stock public FSF sources. With out this change, FreeBSD will be removed from the list of systems GCC 3.0 must be evaluated on before release. With the effort some of us put into getting FreeBSD on this list, we should not turn this effort into a waste, else we might not be worth fighting for in the future. (note that Alpha and IA-64 versions of crt{i,n}.S are needed)
* Switch from our own crt{begin,in} to those created from GCC's crtstuff.c. This will allow us to switch to DWARF2 exceptions in the future, along with staying in sync with any future GCC requirements.
* Break out our ELF branding bits into a seperate file. Currently this is now included by our crt1.c files (since this functionality was part of our native crtbegin.c). Later crtbrand.o will be merged in the creation of crti.o.

Move the code for the ".init" and ".fini" sections outside of a C function so the compiler won't try to emit line numbers for it with "-g", breaking the build. This has the nice side-effect of making crtbegin.o and crtbeginS.o a little bit smaller.

Make profiling work for ELF. gprof now autodetects the format of the executable file, so it will work for both a.out and ELF format files. I have split the object format specific code into separate source files. It's cleaner than it was before, but it's still pretty crufty.
Don't cheat on your make world for this update. A lot of things have to be rebuilt for it to work, including the compiler and all of the profiled libraries.
