It is wrong for gcc to abuse /var/tmp for files that aren't
meaningfully persistent, just like it would be wrong to abuse /usr/bin
for configuration files that the operator is expected to edit.  If
upstream inexplicably insisted on abusing /usr/bin for a configuration
file because it was once on a larger partition than /etc, we would
patch gcc to fix that bug too.

If gcc doesn't respect TMPDIR, that's a separate bug that should be
fixed as well.

We don't need to set TMPDIR=/tmp anywhere because that's already what
correct programs use by default (for example, via _PATH_TMP).
