Make that 2 installs on powerpc.

Somebody else pointed out the obvious, which is that I've not done a
floppy-only install for many years, so it is using the images/files
off the cdrom, so technically I am using those floppies.

Yeah, that's what I said/meant.  The boot-floppy-hfs.img floppy
doesn't work the same way as the rescue floppy does for other
architectures. My point is that for powerpc, the "rescue" function
of the floppy with the word "rescue" in it's image file name is
somewhat impotent.  This can be somewhat confusing if you're not a
graduate of the powerpc debian booting/installing gauntlet.  Most
especially because of the way the generic debian install docs refer
to the rescue floppy for everything.

Wha?  It takes the same amount of time to build a cross gcc as a
native on my machine, namely about 30 minutes.  Maybe you're
thinking of other things that might be required, like libraries and
such.  That might take a while.  ~:^)

And I finally [duh] figured out how to make the floppies in a
reasonable amount of time: instead of make release, make build,
which leaves out the docs.  phew.

Why does this sound way too easy?  I'm gonna have to check that
out.  The other thing is that theoretically, we should be able to
get the hardware to tell us that a floppy has been inserted. 
Possibly only on mac hardware, but hey.  Or we could just poll the
drive or something.  Hmmm, lots of crazy ideas...
