	* configure.host: Detect mips-freebsd and mips-kfreebsd-gnu, and set
	`gdb_host' appropiately.
	* configure.tgt: Detect mips-freebsd and mips-kfreebsd-gnu, and use
	the same definitions as with mips-netbsd.

	* config/mips/fbsd.mh: New file.
	* config/mips/nbsd.mh (MH_CFLAGS): New variable (defines BSD_OSABI
	C macro).

	* mipsnbsd-tdep.c [BSD_OSABI == GDB_OSABI_FREEBSD_ELF]
	(MIPSNBSD_NUM_GREGS): Define as `40'.
	(MIPSNBSD_NUM_FPREGS): Define as `34'.
	(NBSD_MIPS_JB_PC): Define as `12'.

	* mipsnbsd-tdep.c (_initialize_mipsnbsd_tdep): Replace
	`GDB_OSABI_NETBSD_ELF' with `BSD_OSABI'.
