The practical use of a kernel without any device drivers or file
systems is pretty low, I would not expect such a kernel to be
any useful. Having a regular configuration where you just disable
the platform support is a little different. This could happen
when the platform you are building for depends on a specific
feature to be enabled or disabled and that option is accidentally
changed. E.g. when you turn off MMU support on a platform that
depends on having that, we fall back to the default platform
(versatile?). The same may happen when you build for a single
board and one of it's dependencies goes away.
