kernel build hacks for vanilla builds

This is enough for "make vanilla-scratch-build" to work (or vanilla-i686,
vanilla-compile, etc). It might even be enough for "make vanilla-tag
vanilla-build", but I'd have to check it in to test that kludge.
Attached below is my linux-2.6.17-nonintconfig.patch, my old replacement
for linux-2.6-build-nonintconfig.patch (that didn't even need any
rediffing). It adds a second option "make loose_nonintconfig". IIRC, this
is necessary when upstream adds config options not yet in our config-*
files, so you get defconfig answers for new things instead of errors. This
probably doesn't come up with rawhide vanilla builds since those are only
"downgrades", but it can come up when trying builds from GIT branches for
experimental new things, and I found it much nicer to have defconfig win
for this instead of hand-tweak config-foo in my otherwise pristine checkout.
For doing builds from GIT branches, there's some more makefile magic and a
little script to be dusted off. If you like this stuff, I'll check it in
and then fiddle some more for the GIT variant.
Thanks,
Roland
