Bug#944635: jack-tools FTCBFS: hard codes the build architecture compiler

[Helmut Grohne]

Source: jack-tools
Version: 20131226-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

jack-tools fails to cross build from source, because the upstream
Makefile hard codes the build architecture compiler. The attached patch
makes it substitutable and additionally makes debian/rules export cross
tools using dpkg's buildtools.mk to make jack-tools cross buildable.
Please consider applying the attached patch.
