        * config/i386/gnu.h: Include <gnu.h> right after <i386/linux.h>,
        such that we can override its definitions if necessary.
        (CPP_SPEC): New define.  Support processor specific predefines via
        %(cpp_cpu).
        (CC1_SPEC): New define.  Support processor specific compiler
        options via %(cc1_cpu).
        (STARTFILE_SPEC): New define.  Use crt0.o instead of crt1.o for
        -static.
