> This commit allows the user to store defconfigs in
> $BR2_EXTERNAL/configs/. To achieve this:
> 
>  * It adds a new %_defconfig that looks in $BR2_EXTERNAL/configs/ for
>    the corresponding defconfig file.
> 
>  * Updates the help target to also list external defconfigs.

There is no empty line after other help section titles, and the titles
end with a colon, eg.:

---8<--
Miscellaneous:
  source                 - download all sources needed for offline-build
  source-check           - check selected packages for valid download URLs
---8<--
