Bug#843910: cups-pdf FTCBFS: uses build architecture compiler

[Helmut Grohne <helmut@subdivi.de>]

Source: cups-pdf
Version: 2.6.1-21
Tags: patch
User: helmutg@debian.org
Usertags: rebootstrap

cups-pdf fails to cross build from source, because it uses the build
architecture compiler. Defaulting CC to a triplet-prefixed compiler
fixes the build. Please consider applying the attached patch.
