I am not sure I understand: we trust that Libtool, which provides us
with the --disable-shared option, will do the right thing.  And it
seems it does here: the static library is built and passes its checks.

Perhaps you want something different from what --disable-shared promises,
that is, not to build any shared libraries?

Any suggestion about how to improve the PPL is welcome.  This, of course,
applies also to the build machinery.
All the best,
