[Buildroot] [PATCH v2 1/5] system: support br2-external skeleton packages

[Yann E. MORIN <yann.morin.1998@free.fr>]

Brandon, All,

On 2020-10-13 17:36 -0500, Brandon Maier spake thusly:
> Today, the BR2_ROOTFS_SKELETON_CUSTOM is the only way to build a custom
> skeleton. But it's limiting as users must provide a pre-built skeleton
> for each target. Supporting a br2-external package allows users to build
> up a skeleton and customize it with their own KConfig options.
