The library path (`lib/gcc/$triple/$libdir`) still looks weird and I think I don't understand the GCC rationale well.
If you still think it's the right thing the do, let's do it.

For driver tests involving search paths, it's usually worth checking whether the test passes with `-DCLANG_DEFAULT_RTLIB=compiler-rt -DCLANG_DEFAULT_UNWINDLIB=libunwind -DCLANG_DEFAULT_CXX_STDLIB=libc++`.
Some groups use this configuration and expect the tests to pass in this mode.
