	* 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.
