Implement cross build support for embedded devices into
release.sh:

 - Modify release/release.sh to recognize an 'EMBEDDEDBUILD'
   variable.  When set, release/release.sh will build the chroot
   userland as is done for big-iron builds.

 - Instead of running the 'buildworld', 'buildkernel', and
   'release' targets in the chroot, a separate script is run.
   The script tools/release/${XDEV}/release.sh sets up the rest
   of the chroot workspace, such as installing ports that will
   be needed, and building the 'xdev' target.

 - crochet (by kientzle@) is checked out from the upstream
   repository (and if needed, u-boot, in the case of Raspberry
   Pi).

 - tools/release/${XDEV}/release.sh then runs crochet with
   a configuration file specific to the ${KERNCONF} being built.

Note that this is effectively a first-pass attempt to integrate
this into the release process.
