While you're right about sparc64, amd64 is a little different because
you get more registers when you're running in 64bit mode.  I think
there's some other advantages too that actually make up for the fact
that the pointers and whatnot are larger.

Sure, biarch is good, will be useful on amd64 as well as other things
when it eventually happens, but let's get a pure amd64 into the archive
since it's ready to go now.
