Bug#941191: gigalomania FTCBFS: uses build architecture build tools

[Helmut Grohne]

Source: gigalomania
Version: 1.0+ds1-1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

gigalomania fails to cross build from source, because it uses build
architecture build tools. The easiest way of passing cross tools to make
- using dh_auto_build - doesn't fully work here, because gigalomania's
Makefile uses CC for the C++ compiler. The variable needs to be renamed.
Also debian/rules hard codes the build architecture pkg-config.
Supplying a pkg-config from dpkg's buildtools.mk fixes this part. Please
consider applying the attached patch.
