configure.ac: Substitute `with_cpu'.

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.
