- Organization: GCC Team, Red Hat
This patch addresses a number of minor issues in mips64-linux-gnu
specs, that have been reported to me. Pre-approved by Eric
Christopher. I'm checking it in mainline.

from Alexandre Oliva <aoliva at redhat dot com>
* config/mips/linux64.h (DRIVER_SELF_SPECS): Add endian_spec.
Default to -mips3 on -mabi=64. Don't add -mips* flag if -march is
specified.
(SUBTARGET_ASM_SPEC): Remove -mips*-adding code obviated by
DRIVER_SELF_SPECS.
(LINK_SPEC): Let endian options affect the linker emulation name.
