[PATCH, TESTSUITE] Add -fno-short-enums to pr51712

[Kyrylo Tkachov]

Add -fno-short-enums flag to test c-c++-common/pr51712.c as discussed in
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=51712.
This removes the excess warning that caused the test to fail.
Tested in arm-none-eabi configuration. The test now passes.
Comment? Ok for trunk?

Thanks,
Kyrill
