[Pkg-phototools-devel] Bug#944439: libimagequant FTCBFS: uses the build architecture compiler

[Helmut Grohne]

Source: libimagequant
Version: 2.12.2-1.1
Tags: patch
User: debian-cross at lists.debian.org
Usertags: ftcbfs

libimagequant fails to cross build from source. It has a hand-written
configure script that fails to understand the --host flag passed by
dh_auto_configure. Instead, one is supposed to pass a CC assignment.
That mostly fixes the build, except when building from a !x86 to an
x86 architecture: There SSE is supposed to be detected from uname, so
the build becomes unreproducible. Instead, a --enable-sse or
--disable-sse flag should always be passed. Please consider applying the
attached patch.
