It seems a bit ugly that for languages other than Erlang, this change
should be expanded as well.  Likewise for the other changes below.
IIUC the Right Way would be to have a per-language $ac_objext, but that
is much more than I'm willing to tackle right now (and would likely
cause backward compatibility issues); but can we make these changes only
if the current active language is Erlang?
