core-updates has since been merged to master, so this is now a serious
problem for i686 users. It prevents building any system, and therefore
prevents i686 users from applying security updates.

I looked into this, and the problem is that our 'binutils' package on
i686-linux is not configured to support 64-bit instructions.
Here's a proposed patch that I hope will fix the problem, although I'm
unable to easily test it because I no longer use binary substitutes, and
I have not yet built the core packages for i686-linux.
However, I've applied this patch to my x86_64 system, and verified that
it does not cause any problems there.
Would someone be willing to test it and report back?
Mark
