It looks that the patch fixes the issue, though I've got

Another alternative would be to make the behavior different between cross and
native builds. In native builds, --with-gmp{,-lib,-include} would be passed
through to both gcc configury and libjava/classpath (of course, if present,
--with-target-gmp* would override it for libjava/classpath), and for
crosses it would do what the patch does right now (for the patch it means that
for
native it wouldn't add --with-gmp=$with_target_gmp to ac_configure_args if
$with_target_gmp is empty (and similarly for -lib and -include).
