[Pkg-phototools-devel] Bug#845817: optipng FTCBFS: uses the build architecture compiler

[Helmut Grohne]

Source: optipng
Version: 0.7.6-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

optipng fails to cross build from source, because it uses the build
architecture compiler. Simply setting up a CC environment variable
pointing to a triplet-prefixed compiler is sufficient for letting the
handcrafted ./configure pick it up and properly cross compile optipng.
Please consider applying the attached patch.
