Trying to build FUZIX for z80pack.

* Install sdcc from repo
* Clone Alan's git https://github.com/EtchedPixels/FUZIX

Running 'make' in FUZIX with z80pack as target.  It sure is taking a long time.
Start over:
{{{
  $ make -j 8 | tee build_log.txt
}}}
Woohoo!  It seems to have finished!  Now to figure out what was actually built.
Did {{{make all}}} and some more stuff happened.

I can build filesystems using the scripts but unclear how to make a bootable one
