Sorry, I posted the wrong command line. The line I used was:

CONCURRENCY_LEVEL=32 MAKEFLAGS="CC=gcc-4.4" make-kpkg --initrd \
  --config menuconfig kernel-image

I was not trying to build any kind of xen image - config options were as 
in the attached file, very similar to the regular Debian AMD64 kernel 
with tuning for athlon64, pre-emptable kernel, and asynch scsi scanning 
disabled.
