Bug#943749: dmrconfig FTCBFS: hard codes the build architecture pkg-config

[Helmut Grohne <helmut@subdivi.de>]

Source: dmrconfig
Version: 1.1+git20190919.e47491e-1
Tags: patch upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

dmrconfig fails to cross build from source, because the upstream
Makefile hard codes the build architecture pkg-config. Please consider
applying the attached patch to fix that.
