Bug#932931: gif2apng FTCBFS: uses the build architecture compiler

[Helmut Grohne <helmut@subdivi.de>]

Source: gif2apng
Version: 1.9+srconly-3
Tags: patch
User: debian-cross@lists.debian.org
Usertags: ftcbfs

gif2apng fails to cross build from source, because debian/rules uses the
build architecture compiler as a make default. Supplying the value from
dpkg's buildtools.mk is an easy way to fix that. Please consider
applying the attached patch.
