See
http://git.savannah.gnu.org/cgit/libtool.git/tree/tests/no-executables.at

I don't have time to pursue this before Sunday, but there's a GCC PR
that tracks this: in the no-link case, GCC configury needs to seed a
number of cached variables so that Libtool tests aren't run.

If the one you're hitting isn't exposed in the test code above, then we
need to fix Libtool, too.  Otherwise, the libtool.m4 code shouldn't need
changing (IIRC).

Thanks,
Ralf
