success with ZFS on armv7

[fgs%SDF.ORG@localhost]

dear list,

this post is to inform you that it is possible to build 9.2 with MKZFS=yes on armv7. there is nothing special i needed to to do besides just setting MKZFS=yes in mk.conf and rebuilding kernel + userland. the host system is a rpi2b+, kernel was crosscompiled on amd64. of course, on the host system, you'd want to add 'zfs=YES' to rc.conf. i've found that the current ZFS version on NetBSD doesn't yet support ZFS encryption, so i tried setting ZFS up on top of a bunch of CGDs, which also works flawlessly.

n.b. i know this isnt performant (at all). this post is just informational.
