Bug#941142: gexec FTCBFS: uses the build architecture pkg-config

[Helmut Grohne <helmut@subdivi.de>]

Source: gexec
Version: 0.4-2
Tags: patch upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

gexec fails to cross build from source, because the upstream Makefile
hard codes the build architecture pkg-config. The attached patch makes
it substitutable. Please consider applying it.
