Bug#1038715: simutrans FTCBFS: uses build architecture build tools

[Helmut Grohne]

Source: simutrans
Version: 123.0.1-3
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

simutrans fails to cross build from source, because it uses build
architecture build tools. Usually, these are detected by configure and
while that correctly happens for the compiler, it is not forwarded to
the Makefile. In a similar vein, the build architecture pkg-config is
used for discovering freetype2. Since debhelper will only pass cross
tools for a non-derived makefile buildsystem, we need to force that. I'm
attaching a patch for your convenience.
