 A few comments:

- The rule for internal variables being prefixed by BR_ instead of BR2_ is
written down, in some BR developer days report.

- Bikeshed: call the "dir" variable "outputdir" or something that makes it clear
it's the output.

- For the removal of prepare-kconfig, maybe mention that it reverts

- I think it's worth adding a flag that checks if there is any external
toolchain at all, and to put a comment in br2-external.toolchains.in why it is
