empty. Fix that with help from grog.

# 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.
