For -g that might be an issue depending on what ARM needs to do with
uwtable. If it only needs to generate an entry in a table, that is
probably fine. If there are code differences that are needed to make
unwinding work on arm, that probably needs to be attached to a
different option since we really want the generated code with and
without -g to be the same.
