* config/i386/t-linux64: Set MULTIARCH_DIRNAME.
* config/i386/t-kfreebsd: Set MULTIARCH_DIRNAME.
* config.gcc (i[34567]86-*-linux* | x86_64-*-linux*): Prepend
i386/t-linux to $tmake_file;
set default ABI to N64 for mips64el.
* config/mips/t-linux64: Set MULTIARCH_DIRNAME.
* config/rs6000/t-linux64: Set MULTIARCH_DIRNAME.
* config/s390/t-linux64: Set MULTIARCH_DIRNAME.
* config/sparc/t-linux64: Set MULTIARCH_DIRNAME.
* src/gcc/config/mips/mips.h: (/usr)/lib as default path.
