ia64 SMP kernel fails to compile

[Phillip Hocking]

'm getting this compile error when I try to make my first ia64 SMP kernel. My 
config file is here: http://pastebin.com/424912

The error is here:

[root at smp1:/usr/src/sys/ia64/compile/SMP1]#make depend && make && make install
rm -f .olddep
if [ -f .depend ]; then mv .depend .olddep; fi
make _kernel-depend

What is constant-gp and why do I need it? Will it still flip out if I edit 
that out of the makefile?
