Patch

2012-11-20  Matthias Klose  <doko@ubuntu.com>

	* configure.ac: Substitute `with_cpu'.
	* configure: Regenerate.
	* Makefile.in: Define `with_cpu'.
	* config/rs6000/t-linux64: Add multiarch names in MULTILIB_OSDIRNAMES.
	* config/rs6000/t-linux: New file; define MULTIARCH_DIRNAME.
	* config/rs6000/t-fprules (SOFT_FLOAT_CPUS): New macro. Add e300c2
	to the list.
	(MULTILIB_MATCHES_FLOAT): Define in terms of SOFT_FLOAT_CPUS.
	* config/rs6000/t-spe: Define MULTIARCH_DIRNAME.
	* config.gcc <powerpc-*-linux* | powerpc64-*-linux*> (tmake_file):
	Include rs6000/t-linux for 32bit non-biarch configurations.
