    * gcc-ar.c (main): If GCC_EXEC_PREFIX is set in env,
    append program name to it and pass that as first argument
    to make_relative_prefix.  Always pass standard_libexec_prefix
    as last argument to make_relative_prefix.  If
    make_relative_prefix returns NULL, fall back to
    standard_libexec_prefix.
