package: Port zfs package

This still lacks some init scripts to reassemble pools and for other
tasks. For now, I just do:

| disks=$(blkid | sed -n 's,^/dev/\(sd[a-z]\): .* TYPE="crypto_LUKS".*,\1,p')
| for disk in $disks; do
|         [ -b /dev/mapper/$disk ] || cryptsetup luksOpen \
|                 --key-file=/etc/mykeyfile /dev/$disk $disk
| done
| zpool import -a

+Subject: [PATCH] Support for cross-compiling kernel modules
+
+In order to correctly cross-compile, one has to pass ARCH and
+CROSS_COMPILE make flags to kernel module build calls. Facilitate this
+in the same way as for custom CC flag by recognizing KERNEL_-prefixed
+configure environment variables of same name.
