We've never tried XenLinux with an SSP/PIE-enabled version of GCC.
You might want to try adding 
"-nopie -fno-stack-protector -fno-stack-protector-all"
to Linux's CFLAGS in the Linux root Makefile. 

Although perhaps these are already disabled -- Xen itself doesn't
build at all with PIE or SSP turned on.
