Bug#993124: simutrans FTCBFS: uses the build architecture pkg-config

[Helmut Grohne]

Source: simutrans
Version: 122.0-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

simutrans fails to cross build from source, because it uses the build
architecture pkg-config. While the upstream build system allows
substituting pkg-config, it does not do so in a standard way, which is
why dh_auto_build doesn't handle it already. The attached patch
implements it in simutrans' way. Please consider applying it.
