Subject: [PATCH] [llvm-ar] Ignore -plugin option.

binutils ar uses -plugin to specify the LTO plugin, but LLVM doesn't
need this as it doesn't use a plugin for LTO. Accepting (and ignoring)
the option allows interoperability with existing build systems and
make downstream consumers life much easier.

No objections from Rafael on this change.
