Just committed the fix.

The problem was that static libraries were disabled by default when
configure produced libtool from ltmain.sh. That's why SANE own libtool
script didn't work (it had static libraries disabled), while system
one worked. This could be workarounded using '--enable-static' option
to configure, but that certainly not a solution. So I decided to find
the reliable way - to tell libtool that we are going to build static
libraries (liblib.a, libsanei.a). It could be achieved using '-static'
flag during libtool's compile & link stages. The fix I've committed is
based on this approach.

Thanks to all who spent the time locating the problem.
