[Buildroot] [PATCH 1/1] support/scripts/br2-external: add kernel extensions

[Buildroot] [PATCH 1/1] support/scripts/br2-external: add kernel extensions

[Nicolas POIROT via buildroot]

Buildroot documentation section 9.2.1.6 "Additional kernel extensions"
indicates support for kernel extensions defined in external buildroot
trees but unfortunately, there didn't seem to be any support in
br2-external script.
This patch copies 'init' code support to include external kernel
extensions defined in 'linux' dir at the br2-external root directory as
explained in documentation.
