Hi,

libav FTBFS on powerpcspe[1] like this:

[...]
dh_testdir
mkdir -p debian-static
cd debian-static && CFLAGS="-fstack-protector --param=ssp-buffer-size=4 
-Wformat -Werror=format-security" CPPFLAGS="-D_FORTIFY_SOURCE=2" 
LDFLAGS="-Wl,-z,relro" /«PKGBUILDDIR»/configure \
                --arch='powerpc' --enable-pthreads --enable-runtime-cpudetect 
--extra-version='6:0.8.5-1' --libdir=/usr/lib/powerpc-linux-gnuspe 
--prefix=/usr --disable-yasm   --enable-bzlib  --enable-libdc1394      
--enable-libdirac       --enable-libfreetype    --enable-frei0r         
--enable-gnutls         --enable-libgsm         --enable-libmp3lame     
--enable-librtmp                --enable-libopenjpeg    --enable-libpulse       
--enable-libschroedinger        --enable-libspeex       --enable-libtheora      
--enable-vaapi  --enable-vdpau  --enable-libvorbis      --enable-libvpx         
--enable-zlib --enable-gpl --enable-postproc --enable-swscale   
--enable-libcdio        --enable-x11grab                --enable-libxvid        
 
You need a compiler that supports {} in AltiVec vector declarations.
[...]

The attached patch fixes this by assing support for powerpcspe in the Debian
packaging, but omitting Altivec (not available on powerpcspe) in this case.

Thanks,

Roland
