I believe that this 'filtered randconfig' behaviour is now fairly much
the *only* use for the old 'ARCH=i386' and 'ARCH=x86_64'.

Other than that, we ought to finally be able to 'complete' the merge of
32-bit and 64-bit support into ARCH=x86, and remove the last traces of
the obsolete ARCH={i386,x86_64} settings completely? Just as we did for
'ARCH=ppc{64,}' a few years ago.

And as I said, it's still an incomplete solution if you actually want a
'filtered randconfig' to do anything *useful*. You'd be much better off
implementing a *real* filtered randconfig that allows you to give a list
of hard-coded options, rather than relying on a dirty hack that only
actually sets *one* option of the many that you might need to
'hard-code' if you actually wanted a useful build.

So no, I don't think I misunderstood your "regression report" at all.

But go ahead and change the commit message if you must. As long as the
bug gets fixed, I'm content.
