New target/device: Via epia-mii: 

Creates a target for the epia-mii board. Fairly generic, based on 2.6 kernel.
Doesn't override the busybox or uclibc configurations. Includes one patch,
which I still can't get to apply (it applies cleanly manually, but isn't
applied through buildroot).

# Note:  If you have any patches to apply, create the directory

# them in the order you wish to apply them...  i.e.

#

#   sources/kernel-patches/001-my-special-stuff.bz2

#   etc...

#

# these patches will all be applied by the patch-kernel.sh
