Huh? What tests are you talking about? I thought that tests for Clang
driver verifiy that the command "clang++ -fsanitize=address ...." produce a
correct linker invocation (with path to
/lib/clang/3.5/linux/libclang_rt.asan-arm.a), but don't actually require
the libraries to be built there. If it's not the case, we should fix that.
