This patch causes problem for multilib: GCCInstallation.getInstallPath() is
empty in that case and 'clang -m32 foo.c' will put a -L with nothing after it
but the .o file generated, effectively dropping it.
With recent freebsd-lib versions, it is only needed for c++ with libstdc++,
which is actually broken because clang++ cannot find the headers. it is fine
with clang++ -stdlib=libc++.
