OK, I replaced my avr-libc package with the fc10 version, and the
problem goes away, so it seems that the fc9 build of avr-libc was
screwed up somehow. 

__mulhi3 is indeed a software multiply routine for CPUs without the
hardware multiply instruction, so the atmega128 build of libc.a 
should not have tried to call it at all.
