Bug#838317: x264 FTCBFS: configures for the build architecture

[Helmut Grohne]

Source: x264
Version: 2:0.148.2699+gita5e06b9-1
Tags: patch
User: helmutg at debian.org
Usertags: rebootstrap

x264 fails to cross build from source, because it configures the build
for the build architecture. After recognizing that it uses a
hand-crafted configure script, figuring the right flags is pretty
simple. For cross compilation it wants --host and --cross-prefix. Once
giving these options, it crosses just fine (at least for ppc64el).
Please consider applying the attached patch.
