    aarch64: Small config.gcc cleanups
    The aarch64-option-extensions.def parsing in config.gcc had
    some code left over from when it tried to parse the whole
    macro definition.  Also, config.gcc now only looks at the
    first fields of the aarch64-arches.def entries.
            * config.gcc: Remove dead aarch64-option-extensions.def code.
            * config/aarch64/aarch64-arches.def: Update comment.
