Bug#930206: evolver FTCBFS: does not pass cross tools to make

[Helmut Grohne]

Source: evolver
Version: 2.70+ds-4
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

evolver fails to cross build from source, because it does not pass cross
tools to make. The easiest way of fixing that - using dh_auto_build -
does not make evolver cross buildable, because it uses help2man.
help2man is tricky to fix, so I'm only submitting a patch for using
dh_auto_build here. Please consider applying it and close this bug when
doing so. At least it makes parallel building just work.
