I presume you are aware of gnu/112215 (and maybe others).

That's an improvement on my patches (in 112215) - they resulted in
the i386 binaries having references to /libexec/ld-elf32.so.1 and
/usr/lib32/*.so - so they would run in i386 compatibility mode on
amd64 but not on native i386.

I hope to get some time to do this in a few days.
