Hi,
this patch:
- sets DEFAULT_CFLAGS to -O2, if not set otherwise
   (similar to what is done in c.exp)
- removes superfluous dg-options "-O2" settings.
- removes superfluous dg-options "-fopenmp" settings.
- uses dg-additional-options for -std=<standard> settings

Tested on x86_64.

OK for trunk?

Thanks,
