Right, as gcc no longer ignores arguments it doesn't accept.

The "correct" way is to add -no-undefined to lib*_la_LDFLAGS variables
for each library, which is portable and can be sent upstream (despite
popular misconception, this flag is harmless on non-PE targets). If
that's too difficult (e.g. a package won't autoreconf cleanly), then if
LDFLAGS is otherwise empty, then pass LDFLAGS=-no-undefined to cygmake
(or MAKEOPTS).
