Yes, that would seem to be possible too.  I have never used libkver.
You would still need the armv6 userland to get the right compiler as I
would not expect the armv7 compiler to produce proper binaries.

QEMU has some advantages for me, personally, as it means I don't have to
stand up another physical device to do builds.  I run a number of ARM
systems and have been running them all as armv6, even though some of
them are more advanced than that, because it was annoying to do more
than one build of userland and pkgsrc.
