MFC r245133: Only assign the environ in the startup code when environ is NULL.
Note that this is not the merge, but a reimplementation of the fix, done for the not-consolidated code in the stable/9.

MFC r234502:
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.

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.

The main reason for this is to reduce diffs between all the crt1.c's.
Assembler macros are tidied up and made as similar as sanely possible. The macros are translated into C (__inline static) functions for lint.
Declaration orders are made the same. Declarations are all ISOfied and tidied up.
Comment contents have gratuitous diffs removed.
The net result is a bunch of crt1.c's that are 90% the same. It may be possible to now encapsulate the differences in one MD header, and have only one MI crt1.c file (although the macros to do this may be ugly).

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.
