On sparc64: create additional "marker" object files, that can be used by the
compiler to encode the used code model in binaries.

MARCH note is conditional

Add support for a NetBSD MARCH elf note to record the MACHINE_ARCH for
which a program was compiled.

Switch i386 and x86_64 to the new CRT layout. The crt0.c body is shared
between all platforms and a small assembler stub in crt0.S is used for
setting up the proper stack and whatever else MD needs.

Extract crti.S and crtn. from the old dot_init.h files. Prepare other
platforms that use the 6-argument form of __(_)start for this.

Rewrite the crtbegin and crtend modules in assembler to make them
compiler independent. Document the interface in README.
