You are welcome to fix it in whatever way makes sense to you.  I assumed 
that BBv2 already implemented your first option (detecting the host 
architecture), and that's the fix I would favor.

Since all 3 architectures mentioned in gcc.jam use the same gcc options 
for 32-bit vs. 64-bit code, it seems reasonable that gcc would use the 
same options for any future architectures.  So my suggestion shouldn't 
break any builds currently supported, and it works now, not waiting for 
a BBv2 fix.
