spec hacks for vanilla and git-based kernel rpm builds

[Roland McGrath]

Oops, I accidentally checked in my Makefile too.  So I guess I'll just
assume you thought its changes were good.  ;-)

This one copies some extras-style boilerplate that is necessary if you have
a whole-tree checkout of /cvs/pkgs/rpms.  It does not give you individual
foobar/common/ checkouts like it will if you do "cvs co foobar", and the
old extras style was for everything to use your single common/ checkout at
the top.  This is now the standard boilerplate apparently, which every
formerly Core package needs to work with whole-tree checkouts.

The rest (cvs diff -r 1.49 -r 1.50 Makefile) is all additions at the end.
You can use "make vanilla-x86_64" or "make vanilla-prep" or whatnot,
and various git/blah targets.  The details were previously discussed here,
and are in comments in the makefile additions.
