Workaround to build libav for i586 with gcc 4.9.2 by avoiding memset

Description: Workaround to build libav for i586 with gcc 4.9.2 by avoiding
memset
Author: Bernhard Übelacker <bernhardu at vr-web.de>

Hello Fabian, hello Sebastian,
as I tried to get a minimal example which shows this "impossible 
constraints" error I saw that a removal of a seemingly unrelated memset 
made the error go away.
Therefore I tried replacing this memset by a for loop and an assignment 
and that worked too. At least a package built in my i386-chroot compiled 
successfully and the package did not lead to a crash inside the 
i386-qemu-VM (not tested on real hardware).

So probably this could be a better workaround.
