it seems we managed to mess up the configure flags badly here: right now
the buildbots are configured with just CFLAGS/CXXFLAGS=-m64, nothing
more.  I hope the following patch should fix things:

* There's no need for disable_default_compilation_flags = True: the
  default works just fine, we only need to add -O at the moment.  Isn't
  it enough to do this once in RunTestGDBSolaris_Common?

* Obviously the -m64 needs to be appended in RunTestGDBPlainSolaris_c64
  to both CFLAGS and CXXFLAGS to avoid losing the -O above.

* Not in the patch, but wouldn't it be enough to set enable_targets_all,
  make_command, and run_testsuite only once in RunTestGDBSolaris_Common?

Thanks.
