* config/freebsd.h: New, FreeBSD architecture independent file.
        * config/i386/freebsd-elf.h: removed FreeBSD architecturally
        independent pieces.

* configure: Rebuilt.
* xm-i386.h: Define `__i386__' if not defined, rather than `i386'
which is in the user's namespace.
* libgcc2.c: Look for the ANSI-C approved `__i386__' symbol, vs.
