Weird, is it still failing? When I tested it was skipping one configuration and executing the rest.

arm_v8_vfp_ok is supposed to add -mfpu=fp-armv8. When I tried it with dg-add-options it didn't
work because it kept adding more options after the -march=armv8-a and reverting it back to armv7.

The only way I found that seemed to work was skipping the test if not supported.

In principle all I really need to know is if the target has a hardware div, but
check_effective_target_arm_divmod_simode did not seem to work.
