We want to remove libtool-bin from the Debian archive, because it is
fundamentally incompatible with cross compilation. The intended way to
use libtool is to generate one at configure time. This is not how
libtomcrypt uses libtool. Instead, it tries to rely on a pre-configured
libtool. I'm attaching a patch that generates a minimal libtool for
building for your convenience.
