Crazy suggestion: What if we make 32-bit x86 a secondary arch and keep only
x86_64 as primary? ;-)

Of course, that'd be pretty radical and it's likely too early to do that.
(For example, I'm typing this on a 32-bit-only machine (old Pentium IV from
before EM64T).) It'd also most likely mean to drop multilibs from the
x86_64 repo by default (because the 32-bit stuff would be built as a
secondary arch only). But still, it's food for thought, and I'm pretty sure
there will be a point in time where we'll want to do that, considering that
basically all new non-netbook x86 hardware is x86_64.
