fixing PR32765

[Jack Howarth]

   Mike Stump looked at PR32765 and suggested several
ways to fix it. On the link line for the failing tests
libgomp.fortran/pr32550.f90 and libgomp.fortran/crayptr2.f90
we can either use -static-libgcc, -lgcc_s or libgomp.a.
I prefer using -static-libgcc and verified that both
testcases pass when that flag is passed for darwin. The
pr32550.f90 testcase will be trivial to patch. The change...

will suffice. However the crayptr2.f90 testcase is more
problematic since we already have a dg-options comment line.
In c/c++ sources, multiple comment lines for dg-options seem
to co-exist with each being executed. However, I am finding
that when I add...

Only the second dg-options line seems to be used. This makes me wonder
if the dejagnu harnesses for fortran are broken for such multiple
dg-options lines. If so, we will need to find out how to craft a
single dg-options line that achieves both. In any case, if I add...

 ! { dg-options "-fopenmp -fcray-pointer -static-libgcc" { target *-*-darwin* } }

to the crayptr2.f90 testcase it passes so we have the fix as soon
as we figure out the dejagnu syntax appropriate for these fortran
source files.
