One minor concern with that placement is that I enjoy the ability to
nuke a partial or corrupted builds my doing 'rm -rf coreboot/x230',
so having the config file stored in a generated directory would be
problematic.

However, it would be nice to remember the $(obj) and $(DOTCONFIG)
variables when oldconfig is run in an external build.  kbuild generates
a Makefile in the external directory with its equivilant of those
variables preset so that you can run 'make' in the output directory
and have it do the right thing.
