Fix bug in `darwin_test_archs()` when the cache variable is set but empty.
Summary:
If the cache variable named in `${valid_archs}` (e.g. `DARWIN_osx_BUILTIN_ARCHS`)
is set in the cache but is empty then the cache check
`if(${valid_archs})` will be false so the function will probe the
compiler but the `set(...)` command at the end of the function to update
the cache variable will be a no-op. This is because `set(...)` will not
update an existing cache variable unless the `FORCE` argument is
provided.
To fix this this patch adds `FORCE` so the cache is always updated.
