MFC r312452-r312512:
r312452-r312512:
- Use SRCTOP-relative paths to other directories instead of .CURDIR-relative ones
This simplifies pathing in make/displayed output
- Use .CURDIR:H instead of .CURDIR to simplify pathing in output, etc

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.

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.

Work around a binutils bug on powerpc64 where the TOC would not be properly reloaded when calling _fini() in large binaries with multiple TOC sections (e.g. GCC), leading to a segmentation fault. Adding -mlongcall to crt1 flags causes the compiler to emit explicit TOC load instructions for all function calls, including _fini().

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.

Properly support -fPIE by linking PIE binaries with specially-built Scrt1.o instead of crt1.o, since the later is built as non-PIC.
Separate i386-elf crt1.c into the pure assembler part and C code, supplying all data extracted by assembler stub as explicit parameters [1]. Hide and localize _start1 symbol used as an interface between asm and C code.

Major cleanup of bsd.lib.mk.
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB. INTERNALLIB now means to build static library only and don't install anything. Added a NOINSTALLLIB knob for libpam/modules. To not build any library at all, just do not set LIB.

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.
