It should work fine. It does with the base kernel from
kernel.org and I
do this all the time.
Unfortunately, the problem is still there. Here is a grep for 'ELF
64' from the output of the file command run over the installed list of
files from kernel-devel built on an x86_64 system, running on an i686
system.

It's too bad. That would have simplified the build pross
considerably.
