Hi.

  This patch removes obsoleteOVERRIDE_OPTIONS macro from the MIPS back end in
the GCC and introduces equivalentTARGET_OPTION_OVERRIDE target hook.

  Bootstrapped and regression tested on mips64el-unknown-linux-gnu.

        * config/mips/mips.c (mips_override_options): Rename to...
        (mips_option_override): ...this. Make static.
        (TARGET_OPTION_OVERRIDE): Define.
        * config/mips/mips.h (OVERRIDE_OPTIONS): Remove.
        * config/mips/mips-protos.h (mips_override_options): Remove.

Anatoly.

Please also change the reference to mips_override_options in
mips_in_small_data_p.  OK with that change, thanks.  Rebuilding
mips.o is enough to test the comment change.

For the record, I realise we still have SUBTARGET_OVERRIDE_OPTIONS
for VxWorks, but that's OK IMO.
