Subject: cross-compiling a 64-bit kernel on a 32-bit host

Hi Fengguang,

I occasionally get compilation bug reports from people who are
cross-compiling an x86-64 kernel target on an x86-32 host.

Any chance the 0-day build bot could test that configuration?  I think
just building a defconfig would be sufficient.  It would help sort out
issues in objtool and other host-built scripts.
