Neil Blakey-Milner d295906767 First part of PicoBSD makeover, adding basic 'obj' facilities, allowing
for read-only src tree.

While I'm there:
1) Use kgzip, not kzip, since kzip certainly doesn't make bootable
kernels anymore.  loader still isn't built separately, let alone without
forth support.  This needs to be fixed.

2) Expand the mount/vnconfig examples to be the defacto way of making
sure the filesystems are mounted, unmounted, or not configured.  This
needs more work.

3) quieten the build substantially, so errors are more prominent

4) Start of '-j' ability.  Current style isn't quite in the correct
dependency format for this, but obvious mistakes (changing directories
in main shell) are fixed.

Approved by:	grog, dwhite, luigi (no objections to me doing a makeover)

# Building a PicoBSD kernel involves four basic operations:
#
# 1. Build a kernel. This is done by the 'kernel' target.
# 2. Build a PicoBSD file system. This file system is loaded into an
# MFS at boot time. This is done by the 'fs' target.
# 3. Build a single executable file for all the programs, and install it in
# the mfs image. This is done by the 'crunch' target.
# 4. Build a floppy image containing the MFS image and some helper code
# to boot it. This is done by the 'image' target.
# 5. Copy the image to the floppy. Done by the 'copy' target.
# You can set the SRC variable which points to your source tree. It's
# /usr/src by default (most people shouldn't change it).
