CMake: Fix sanitizer build when using Clang on Linux
Apparently the combination of the --no-undefined linker flag together
with ASAN when building on Linux with Clang does not work.
Disable --no-undefined flag in such a scenario. Note that linux-clang
mkspec doesn't add that flag at all, which is why asan builds work
there.
