--- Comment #4 from Peter Bergner <bergner at gcc dot gnu.org> ---
So it seems rs6000_pragma_target_parse() ends up calling
rs6000_option_override_internal(), which is modifying the options via global
variables.  All other arches pass in the option variables to their
*__option_override_internal(), that they want updated/set and those seem to be
scoped to the area of the file they reside in.
