Bug#760433: libav: FTBFS on x32: Invalid inline assembly

[Daniel Schepler]

Source: libav
Version: 6:11~beta1-2
Severity: important
Justification: blocker for kde builds
X-Debbugs-CC: Thorsten Glaser <tg at mirbsd.de>

When I try building libav in an x32 schroot (without the build dependencies on
frei0r, opencv, x264 which have also all failed to build on x32), I get this:

...
/tmp/libav/libav-11~beta1/libswscale/x86/swscale_template.c: Assembler messages:

debian/rules:81: recipe for target 'build-stamp-static' failed
make: *** [build-stamp-static] Error 2
rm configure-stamp-static
dpkg-buildpackage: error: debian/rules build gave error exit status 2

I'm attaching the debdiff I'm using for an upload to debian-ports/unreleased.
You can ignore the debian/control part, and as the debian/rules changes could
be considered a horrible hack, I'm not tagging this as patch.
