True, but some of the target libraries require *running* the resulting
64-bit executables, which still fails in such a configuration.  Besides, in
many cases hosts that don't support a 64-bit kernel (or where only a 32-bit
kernel is installed), the 64-bit system libraries are not installed either.

I'd suggest that unless we have positive reports that a full bootstrap for
both 32-bit and 64-bit multilibs works on a system with a 32-bit kernel,
but 64-bit system libraries installed, we keep that sentence.
