  Hi,

When running gdb.python/lib-types.exp, we have an xpass:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
typedef_const_typedef_class1_ref^M
(gdb) XPASS: gdb.python/lib-types.exp: \
  python print (str (typedef_const_typedef_class1_ref_obj.type)) \
  (PRMS gcc/55641)
...

When running the same with gcc 4.8, we have an xfail instead:
...
(gdb) python print (str (typedef_const_typedef_class1_ref_obj.type))^M
const typedef_const_typedef_class1_ref^M
(gdb) XFAIL: gdb.python/lib-types.exp: \
  python print (str (typedef_const_typedef_class1_ref_obj.type)) \
  (PRMS gcc/55641)
...

It's incorrect to xfail a gdb test-case for gcc bug.

Marking the test unsupported for older gcc instead is not necessary either:
it's just that gdb prints different output when given different input, which
is entirely expected behaviour.

Fix this by passing for both patterns.

Tested on x86_64-linux, with:
- gcc 7.5.0
- gcc 4.8.5
- clang 5.0.2

OK for trunk?

Thanks,
- Tom

I think we've used "kfail" for this in the past, though TBH I never
truly understood the kfail/xfail distinction and I probably have it
backward or something.

This is ok.  Thank you.
