It seems Clang standalone build does not run config-ix.

Clang tests rely on TARGET_TRIPLE to exclude some tests on certain hosts.
(eg. some tests are maked as "XFAIL: win32" and tests expect "*-win32" as
triplet.

FYI I am checking clang standalone build with setting CLANG_PATH_TO_LLVM_BUILD
to "Installed" LLVM.

Dirty workaround;
