	* config.gcc: Add FreeBSD/PowerPC target.
	(powerpc64-*-linux*, powerpc-*-sysv*, powerpc-*-netbsd*,
	powerpc-*-chorusos*, powerpc-*-eabiaix*, powerpc-*-eabisim*,
	powerpc-*-elf*, powerpc-*-eabi*, powerpc-*-rtems*,

	powerpcle-wrs-vxworks*, powerpcle-*-sysv*, powerpcle-*-elf*,
	powerpcle-*-eabisim*, powerpcle-*-eabi*, powerpcle-*-solaris2*): Add
	freebsd-spec.h to tm_file.
	(rs6000-*-lynxos*): Add lynx.h to tm_file.
	* config/freebsd.h: Tidy up.
	(USING_CONFIG_FREEBSD): Define.
	(FBSD_SWITCH_TAKES_ARG, FBSD_WORD_SWITCH_TAKES_ARG,
	FBSD_CPP_PREDEFINES, FBSD_CPP_SPEC, FBSD_STARTFILE_SPEC,
	FBSD_ENDFILE_SPEC, FBSD_LIB_SPEC): Remove (moved to freebsd-spec.h).
	(TARGET_HAS_F_SETLKW): Define.
	(ASM_OUTPUT_IDENT): Delete, the elfos.h definition is fine.
	* config/freebsd-spec.h: New file.
	* config/rs6000/freebsd.h: New file.
	* config/rs6000/rs6000.h (TARGET_VERSION): Do not define.
	* config/rs6000/rs6000.c: Test for USING_ELFOS_H rather than
	USING_SVR4_H to know when to turn on ELF support.
	* config/rs6000/sysv4.h (TARGET_VERSION, CPP_PREDEFINES): Don't undef,
	define only if not already defined.
	Add FreeBSD support.
	* config/rs6000/aix.h (TARGET_VERSION): Define.
	* config/rs6000/beos.h: Likewise.
	* config/rs6000/darwin.h: Likewise.
	* config/rs6000/mach.h: Likewise.
	* config/rs6000/lynx.h (TARGET_VERSION): Likewise.
	Don't include lynx.h directly.
