It's usually better to modify configure.in/aclocal.m4 and then rebuild
configure, but I see what you're trying to do.  I picked up these macros
from the libiconv distribution, so I'll have to take a look at what that
distribution needs to inhibit searching for static libraries.  It's
probably something as simple as setting a different shell variable in
configure.

Sure, I'd be interested in taking a look at your patches.  Note that this
is mostly a linux-specific issue.
