The problem is the manual states:

       -t     interpret TEMPLATE as a single file name component, relative to a
              directory:  $TMPDIR, if set; else the directory specified via -p;
              else /tmp [deprecated]

Thus if -t is used and TMPDIR is set, mktemp will ignore the directory
gave via -p.

How about just removing -t here?  It's deprecated anyway.
