User: helm...@debian.org
Usertags: rebootstrap
libmpeg3 fails to cross build from source, because it uses the build
architecture compiler. After letting dh_auto_build pass cross compilers
to make, the build proceeds a lot further but fails on errors from
debian-build-rules.patch. It confuses the build architecture (dpkg
--print-architecture or DEB_BUILD_ARCH) with the host architecture
(DEB_HOST_ARCH) and hard codes the build architecture compiler (gcc).
After fixing all of that, libmpeg3 cross builds successfully. Please
consider applying the attached patch.
