Are there usage cases where someone links a program or library with
libtool, and this uses a libgnu.a rather than a libgnu.la?  If not,
then you can drop LIBGNU_LTLIBDEPS -- libtool will cause the right
thing to happen, independently of whether libgnu.la is a convenience
archive, static library, or shared library.

They could use the lib-ignore module (when they don't use Libtool).
