avfilter/vf_pullup: 2nd try to workaround gcc 4.4.3 bug on arm

Browse Source 
The first try failed to work with some build flags

The gcc version affected is very old and unmaintained AFAIK thus i made no
attempt to report this to the gcc developers.

The workaround is pushed as it may still affect users and does affect one
fate client
