Bug#926498: blastem FTCBFS: builds for the wrong architecture

[Helmut Grohne]

Source: blastem
Version: 0.6.3-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

blastem fails to cross build from source, because it builds for the
build architecture. It does not pass any cross tools to make. The
easiest fix here is using dh_auto_build. Then the upstream Makefile hard
codes the build architecture pkg-config. It needs to be made
substitutable. The attached patch makes blastem cross buildable. Please
consider applying it.
