Stuart, the following is a patch to current ltib to do:

1) If you run "./ltib -b --hostcf" it won't ask to Drop a package that
is deselected in the host configuration
2) If config/platform/host/ltib.preconfig is newer than
config/platform/host/{.config,host.config} it will copy
config/platform/host/ltib.preconfig into config/platform/host/.config

With this change, I can now run "./ltib -b --hostcf" as part of my
buildbot and changes in config/platform/host/ltib.preconfig will take
effect in that build.  Then I can run "./ltib -b --preconfig
config/platform/<platform>/defconfig" and everything just works.

I'm loathe to distclean on my buildbot setup since that causes LTIB to
unecessarily rebuild packages (and I don't want to do that for every
build done by buildbot).
