 I don't know if that is so important. If you really need that, you can still
use OVERRIDE_SRCDIR or copy it to BR2_EXTERNAL under a different name or add a
patch in BR2_GLOBAL_PATCH_DIR.

 Ah, that is a reason to allow versions! But then I'd limit it to three
versions, selectable with a choice: stable (default), next, and old (3.14).

 I don't think a check of the kernel version is needed. There are also
dependencies in a bunch of other modules packages and those don't do a
dependency check either. You can anyway only do that check while building
(because you need to have the kernel source to extract the version), and usually
the modules package already does a check itself.

 That's kind of superseded by BR2_GLOBAL_PATCH_DIR.

 That one would be useful, so a fourth version in the choice.
