[cfe-commits] Patch to support gold on FreeBSD

[Chandler Carruth]

Cool.

First, this needs a test in the 'test/Driver/...' tree. Likely with other
BSD 'ld' invocation tests. There are lots of examples to crib from, in
particular the Linux ones.

Second, can we factor out the logic to add the actual plugin flag? It
should already exist somewhere for Linux?
