For reference, I've used the following script to test libav:
#!/bin/sh
set -ex
if ! test -d libav
then
git clone -b release/10 git://git.libav.org/libav.git
fi
cd libav
build_dir=`pwd`/.build.`cat RELEASE`
mkdir -p $build_dir && cd $build_dir
../configure --enable-shared --enable-gpl --prefix=`pwd`/local # --enable-pic
make -j4 all V=1
make install
export LD_LIBRARY_PATH=`pwd`/local/lib
ulimit -c unlimited
`pwd`/local/bin/avconv -codecs

Subject: [libav-devel] [PATCH] configure: enable PIC on s390(x)
To: libav-de...@libav.org
The s390 architecture requires shared libraries to be built in PIC mode.
Otherwise applications will get wrong relocations at run-time, leading
to confusing segmentation faults.
