OK.

Libtool 1.5.26 is old, and the 1.5 branch not maintained any more.
We have arrived at 2.4, please consider updating.

That said, I *think* that this should have worked with 1.5.x already;
but you need Automake >= 1.10 for support of the *_LIBTOOLFLAGS special
variables.  I'm guessing that you have an older Automake, because the
following minimal example gets me a libfoo that is not built statically.

Please report whether it does for you, and if you get a static libfoo.a,
please try to modify the example so it exposes the failure in your
setup.

Thanks,
Ralf
