The reason why it works on sparc is probably because Debian only
supports sparcv9 (TTBOMK), which has the timer functions implemented in
opal/include/opal/sys/sparcv9/timer.h. The build log also reads:
checking for asssembly architecture... SPARCV9_32

The reasoning for reassigning was that Open MPI built fine on alpha
before (first breakage in 1.2.8), so something has changed. I'm still
trying to find out what.
Thanks for investigating the issue!
