Oh no. The progname module is there to simplify things for both programs and
test suite.

It would be better the other way around: Let m4 use the 'progname' module.

If you feel that it contains too much code (like the libtool workaround),
make this code conditional. In [1] you mentioned a way to detect whether
libtool is used; you can use that to enable the libtool-specific code
in progname only when libtool is used.
