Is it repeatable?  i.e. If you run 'make' again, do you get the same error at
the same place?  If you answer 'no', swap out all your RAM and try again.
Unexplained sig11's are the classic first symptom of failing memory, soon followed
by filesystem corruption and data loss.  I wish I'd paid attention when I had my
first weird crash. :(

(there are other possibilities, but they usually won't be fixed by replacing the
memory and usually will be repeatable.)
