Public bug reported:

I just tried to cross-compile mythtv-frontend for the "armhf"
architecture (via "dpkg-buildpackage -b -aarmhf"). Sadly the resulting
package contained i386 binaries.

The problem seems to be caused by the following lines in debian/rules:
 DEB_BUILD_ARCH ?= $(shell dpkg-architecture -qDEB_BUILD_ARCH)
 ifeq "$(DEB_BUILD_ARCH)" "i386"
         MYTHTV_CONFIGURE_OPTS +=  --cpu=i686 --enable-mmx --disable-xvmc  --enable-vdpau
 endif

This code is doomed to fail under any cross-compile situation since it uses the host architecture (not the target architecture).
Instead of using "dpkg-architecture" it would be probably better to use the environment variable "DEB_BUILD_ARCH". But I don't know if this would be the proper approach.

Please ignore this bug report if cross compilation is not supposed to be
a goal for Ubuntu packages.

cheers,
Lars
