I don't completely agree.
 - I regularly do cross builds.
   What will you do for that? Assume the old version? I think so. Since the
result works the same on all versions. So you might as well just do that for
cross and native imho.

 - I want to build a gcc on 2.10 that works on 2.9..er..well, that's not quite
right. For that I'll build it on 2.9. But the cross build scenario is relevant.

 - Look at what Darwin/Macho does -- that is also only for older versions, but
they just do it unconditionally. (Might be good to check for TARGET_64BIT
though, since that probably implies a new enough assembler?)
