don't override TMPDIR with /tmp on cygwin, cleanup TMPDIR/TMP handling

on cygwin, configure forced TMPDIR to /tmp, regardless whether it is set
or not. And while it respects an existing value of TMP, TMP is only used
in a few places. Changes the ones that explicitly check for TMP to
prefer TMPDIR, and don't duplicate configure's check in other scripts.
