[Buildroot] [PATCH] br2-external: make it available to post-{build, image} scripts

[Yann E. MORIN]

Currently, BR2_EXTERNAL is not always exported to sub-processes that we
spawn, like post-build or post-image scripts. This all depends on how
the user passes BR2_EXTERNAL; consider the following:

- make BR2_EXTERNAL=/path/to/br2-ext
- BR2_EXTERNAL=/path/to/br2-ext make

In the first case, it is just a make variable, not an environment
variable, and thus not exported, while in the second case it is an
environment variable and gets exported to all sub-processes make may
spawn.

Explicitly export it using EXTRA_ENV.

Committed, thanks.
