[Debian-lego-team] Bug#928898: t2n FTCBFS: multiple reasons

[Helmut Grohne]

Source: t2n
Version: 0.6-6
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

t2n fails to cross build from source, because it does not pass cross
tools to make. The easiest way to fix that - using dh_auto_build - is
not sufficient here, because the Makefile hard codes gcc in one place
and uses a non-standard compiler variable name "LK". The attached patch
fixes all of that. Please consider applying it.
