[PATCH #3] mips*-kfreebsd-gnu support in GAS

[Robert Millan <rmh at gnu dot org>]

This patch adds mips*-kfreebsd-gnu (and mips*-freebsd)
support to GAS.

ChangeLog entry included with patch header.

2010-12-14  Robert Millan  <rmh@gnu.org>

	* config/tc-mips.h (TARGET_SUFFIX): New macro, adds a
	"-freebsd" suffix to FreeBSD targets.
	* config/te-tmips-freebsd.h: New file.  Includes tc-mips.h
	after defining TE_FreeBSD to enable FreeBSD version of
	TARGET_SUFFIX().
	* config/tc-mips.c (mips_target_format): Wrap traditional MIPS
	targets around TARGET_SUFFIX().

	* configure.in: Recognize mips-freebsd and mips-kfreebsd-gnu.
	* configure.tgt: Likewise.
	* configure: Regenerate.
