$(STRIP) always expands to something, because it is one of the commands
in the BRIEF list. This renders the condition pointless.

Fixes out of array read

This issue can be reproduced with:
Lucky.asf
teuflisch.asf
from http://samples.ffmpeg.org/A-codecs/VoxWare/

as well as other samples

fcb16m has 320 elements but the code before the patch can address a
table of 384 elements in its place.
I dont know if theres some elements missing, or its maybe the wrong
table, or if the parameters affecting the table size are wrong, or
if theres something else wrong.
if someone reading this has easy access to some reference. (binary
with the tables in it, spec, whatever, please contact us)

This solution fixes the inconsistency by padding the table with zeros,
this variant was suggested by Vitor Sessak. And ensures that nothing
currently working breaks.

That makes avformat & avcodec thread safe without the need to explicitly
register a lock manager.
