config.gcc (powerpc-*-gnu-gnualtivec*, [...]): New configurations.

2002-01-21  Roland McGrath  <roland@frob.com>

        * config.gcc (powerpc-*-gnu-gnualtivec*,
        powerpc-*-gnu*, powerpc64-*-gnu*): New configurations.
        * config/rs6000/gnu.h: New file.
        * config/rs6000/sysv4.h (SUBTARGET_OVERRIDE_OPTIONS):
        Grok "gnu" in rs6000_abi_name.
        (ASM_SPEC, CC1_SPEC, LINK_START_SPEC, LINK_OS_SPEC,
        CPP_ENDIAN_SPEC, CPP_SPEC, STARTFILE_SPEC, LIB_SPEC, ENDFILE_SPEC):
        Grok -mcall-gnu analogous to -mcall-linux et al.
        (LIB_GNU_SPEC, STARTFILE_GNU_SPEC, ENDFILE_GNU_SPEC,
        LINK_START_GNU_SPEC, LINK_OS_GNU_SPEC, CPP_OS_GNU_SPEC): New macros.
        (SUBTARGET_EXTRA_SPECS): Add *_os_gnu specs using them.
