That's the relevant part I found in ffmpeg svn's configure script:

# set temporary file name
if test ! -z "$TMPDIR" ; then
    TMPDIR1="${TMPDIR}"
elif test ! -z "$TEMPDIR" ; then
    TMPDIR1="${TEMPDIR}"
else
    TMPDIR1="/tmp"
fi

As one can see it looks for $TMPDIR and $TEMPDIR, so basically I think adding 
a $TMP check here should be fine as I haven't found $TMP anywhere else in 
configure.

I guess with the above mentioned change we don't need this anymore, right?

Grs,
