These are the same script, which definitely suffers from the problem.

Fixed in the TeX-live sources, at least.

Has problem.

Perl script, has problem.

Perl script, I believe it has the problem.

mktex.opt is a false positive.  The full sequence of commands is given
below:

if test -n "$TMPDIR"; then
  TEMPDIR="${TMPDIR}/mt$$.tmp"
else
  TEMPDIR="/tmp/mt$$.tmp"
fi
