Are these documented somewhere?  I see _topdir is used on
http://wiki.laptop.org/go/Rebuilding_OLPC_kernel (and not really
described) but a quick web search did not reveal any pages that list
these options or describe what they do (although the latter can be
inferred from the variable names).

In any case, the list above and what's on "Rebuilding OLPC kernel"
should be enough information for me to start building RPMs.  The
2.6.26-rc2 boot problems I'm experiencing still remain to be solved.
Let me know if there's anything I can do to provide more information.
