* config/freebsd.h: New, FreeBSD architecture independent file.
* config/i386/freebsd-elf.h: removed FreeBSD architecturally
independent pieces.
* config/i386/freebsd.h: include i386/perform.h via tm.h rather than
directly by i386/freebsd.h.
* configure.in (*-*-freebsdelf): Include new FreeBSD architecturally
independent configuration file.
(*-*-freebsdelf): Include i386/perform.h via tm.h rather than
directly by i386/freebsd.h.
* configure: Rebuilt.
*POTFILES.in: Add config/freebsd.h
