Bug#958134: pd-iemutils FTCBFS: uses the build architecture compiler as a make default

[Helmut Grohne <helmut@subdivi.de>]

Source: pd-iemutils
Version: 0.0.20181004-1
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs

pd-iemutils fails to cross build from source, because it uses the build
architecture compiler as a make default in debian/rules. Please consider
applying the attached patch to let dpkg's buildtools.mk properly
initialize the relevant variables for cross compilation.
