[PATCH v2 0/3] INSTALL updates

I'm now up to a three patch series for this minor documentation update. :-/

The first one simply removes the references to code that no longer exists in our tree. This paragraph will be changed again in 3/3 so this patch could be dropped, but I left it since the factual error is a different issue than the later enhancements.

The second patch mostly reorders the text so that later changes are more obvious. It does contain the changes Junio suggested regarding shell and perl, since the old wording is archaic and confusing to new users.

The third contains the additions concerning the Makefile switches. It has been updated based on Junio's commends.

Brian Gernhardt (3):
  INSTALL: Update description of our SHA-1 code
  INSTALL: Reorder dependencies, split shell and Perl
  INSTALL: Describe dependency knobs from Makefile
