* 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.
