Subject: [PATCH] Fix tests failing on fuchsia clang x86_64 builders

Fuchsia sets CLANG_DEFAULT_UNWINDLIB to libunwind. As a result, when
rtlib is set to libgcc and unwindlib is not explicitly specified, tests
using Fuchsia as the default platform will fail. To address this, the
affected tests are xfailed.

This change fixes the following tests introduced in 45ea46c:

clang/test/Driver/aarch64-toolchain-extra.c
clang/test/Driver/arm-toolchain-extra.c
clang/test/Driver/aarch64-toolchain.c
clang/test/Driver/arm-toolchain.c
