The Driver only checked if nostdlib was set when deciding to add
reserved_lib_stdcxx, but as nostdlib is always exactly nodefaultlibs and

case) as well. This appears to be the only such instance of this in the
codebase.

Our internal buildbot just failed because the tempfile happened to be named
'nodefaultlib-lcGA7k.o', which contains the substring '-lc'.
