* config.guess: Execute $dummy, not ./$dummy, throughout.
* config.guess (set_cc_for_build): Create a chmod 700 directory in
/tmp (or $TMPDIR, if set) to store temporary files generated for
use by the C compiler. This should resist the /tmp symbolic link
use by the C compiler. This should resist the /tmp symbolic link
race vulnerability reported by Lawrence Teo.
