This file doesn't exist on either of
my other two ia64 boxes, where this problem
is not present.

No, I don't think so, gcc from ports don't build
on ia64, at least 43/44/45 don't. I haven't
tried 46 yet. Obviosly clang doesn't build either.

Compare this with the output from another ia64 -current,
where this problem is not present:

$ strings $(which cc) | grep -w tmp                                          
/usr/obj/usr/src/tmp/usr/bin/

/usr/obj/usr/src/tmp/usr/libexec/
/usr/obj/usr/src/tmp/usr
/var/tmp/
/var/tmp

/tmp
$

which seems identical.
