I'm not sure I entirely grok your comment. This choice is only visible
for external toolchains, not for the internal backend, so there is not
two choices to set the kernel headers version.

However, I can indeed add a help entry like that one:

    help
      Set to the kernel headers version that were used to build
      the external toolchain.

      This is used to hide/show some packages that have strict
      requirements on the version of kernel headers.

What do you think about that? Does it answers your concerns?

Thanks for the review! :-)

Regards,
Yann E. MORIN.
