It sounds like while gcc supports the -fPIE and -pie options they
don't actually work properly.  The simple solution is to add
--disable-pie to the configure args for ia64 in the port's Makefile.
I'll also add a configure check to disable PIE on FreeBSD/ia64 in
the next sudo release.

However, you might want to involve the FreeBSD/ia64 folks and see
if they can fix the underlying issues that prevent PIE from working
properly.
