[Pkg-clamav-devel] Bug#1122156: tomsfastmath: stop using libtool-bin

[Helmut Grohne]

Source: tomsfastmath
Version: 0.13.1-2
Tags: patch
User: debian-cross at lists.debian.org
Usertags: cross-satisfiability

We want to remove libtool-bin from Debian. A key reason is that use of
this package universally breaks cross building. The way libtool is meant
to be used is that one is constructed during build using autoconf. The
other route is doing by hand what libtool does. Neither of these routes
is particularly attractive in case of tomsfastmath. Hence, I am
proposing adding a small dummy autoconf project to the debian directory
just to construct a working libtool without using libtool-bin. I'm
attaching a patch for your convenience.
