Testing --as-needed should fail with the OS X linker whether we're using Xcode *or* Boring Old Makefiles, as it doesn't support --as-needed.

And we *do* test it.

I'll try to figure out why it's being included - either the test isn't failing and we need to trick the clang into not just whining about it but actually *failing*, or the test is failing with the Makefile generator but not with the Xcode generator.

This is what I am also tracking down. It has to do with the way cmake is instantiating the compiler. The --serialized-diagnostics option is what appears to be hiding the error.
