So this is unlikely to be a problem with Automake (as the flags specified
at configure time have been passed correctly to the libtool invocation at
make runtime, as you noted).  Thus I suggest you try to report your issue
to the libtool list instead, to see if they have more ideas.  So save you
time, I've already CC:ed the libtool list in this reply.

And, for completeness, what autoconf and libtool versions?
