config.gcc (mips*-*-linux*): If 'enabled_targets' is 'all'... 

2011-07-11  Arthur Loiret  <aloiret@debian.org>
            Matthias Klose <doko@debian.org>

        * config.gcc (mips*-*-linux*): If 'enabled_targets' is 'all', build
        a tri-arch compiler defaulting to 32-bit (ABI o32). In this case:
        (tm_file): Add mips/linux64.h.
        (tmake_file): Add mips/t-linux64.
        (tm_defines): Add MIPS_ABI_DEFAULT=ABI_32.
        * config/mips/linux64.h (DRIVER_SELF_SPECS): Use MULTILIB_ABI_DEFAULT
        instead of hardcoded mabi=n32.
        * config/mips/t-linux64 (MULTILIB_DIRNAMES): Set to 'n32 . 64' if
        tm_defines contains MIPS_ABI_DEFAULT ABI_32, to follow the glibc
        convention.
