I think the main questions here are 1) how to handle optional build tool
dependencies, and 2) whether Python is an optional or required
dependency.

It might be nice to be able to have an actual Kconfig and dependency for
optional tools. "depends on TOOL_PYTHON" or something. Enable the
option, and you should have Python.

This in turn raises the question for allyesconfig. It's cumbersome
(though not impossible) to add config options that you actually have to
enable manually.

The header test stuff really isn't required to actually build the kernel
or drm, however DRM_MSM does depend on Python for building the driver.

Jani.
