I've always built it on the target. In order to make kernel
development work easy, i generally use Debian on everything. Sometimes
with a USB stick, or a big MMC card, sometimes NFS root. Once the
kernel works, then i will move to the production environment, which
generally makes a poor development environment, so should be avoided
as much as possible.

It should be possible to cross compile it, since it uses autotools.
