* 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
