   apmd: Use libtool --tag options to avoid problems with libtool 2.2.4 (from poky)

However I didn't see same issue with current libtool-2.2.10. Also per my understanding,
the default tag, if not specified, falls back to CC. So disable it from patching, but
keep it here. If we encounter similar issue in the future, we could then push upstream
