Whee!  During a guest make -j4 build of glibc.

On top of Alex's latest patch set all that is required for basic success is an 
update to the alpha bios.  Which until today didn't support smp at all.

There does appear to be a problem with delivery of ISA interrupts for smp, 
regardless whether mttcg is enabled or not, though PCI interrupts are working 
fine.  This appears in that both serial console and ps2 keyboard are 
non-responsive, but one can ssh into the guest.  Which doesn't make a whole lot 
of sense.  More debugging required, I suppose.

I'll post the palcode update once the mttcg patch set is merged.
