Slackware uses $TMP for both installing and creating packages. That's where I 
ran into an issue with ffmpeg as there's only a value for $TMP set and not 
for $TMPDIR or $TEMPDIR. (user had /tmp set to noexec, defined another 
tmp-location via $TMP, but ffmpeg still wanted to execute files in /tmp as 
$TMP was obviously not handled)

Further research on google showed that Windows uses TMP alongside TEMP, and 
some unix software prefers $TMP over $TMPDIR, though wikipedia indeed said 
TMPDIR is the standard and others are mostly used on non-posix systems.

I don't think this patch should cause any problems. However, if there are any 
objections on applying the patch I would also be able to work around it in my 
build script. I would prefer it being handled by ffmpeg though.

Grs,
Heinz
