These can be fixed for darwin by passing -Wl,-undefined,dynamic_lookup on
dg-options as has been
recommended by the darwin linker maintainer. Note that this should work for
Xcode 3.2.6 and Xcode 4.4.1
and later. Between Xcode 4.2 and 4.4.0, radr://10466868, "-undefined
dynamic_lookup linker bug", broke
weak symbol dynamic lookup in the linker. Tested on x86_64-apple-darwin12. Okay
for gcc trunk?

* testsuite/libgomp.c++/pr24455.C: Use -Wl,-undefined,dynamic_lookup on
darwin.
