A lot of the unit tests make use of the C++ thread library but the
cmakefile doesn't explicitly link them to the pthread library but
instead rely on hipcc to implicitly link in the pthread library.
Some tests that rely on librt have a similar issue. The tests
break when we are cleaning up hipcc by removing the implcit linking
to those libraries.
