Hi all,

[ Cc Kanak, Edgar involved in a fix for an old version [2] ]

> - reference environment variables directly (remove 'option env='), see
>   upstream commit [1]:

>   BR2_VERSION --> BR2_VERSION_FULL
>   BR2_HOSTARCH --> HOSTARCH
>   BR2_SKIP_LEGACY --> SKIP_LEGACY

I'm very sorry for late reply.

Unfortunately this patch does not apply:

error: patch failed: Config.in:15
error: Config.in: patch does not apply
error: patch failed: toolchain/toolchain-external/toolchain-external-arm-aarch64-be/Config.in:1
error: toolchain/toolchain-external/toolchain-external-arm-aarch64-be/Config.in: patch does not apply

error: patch failed: toolchain/toolchain-external/toolchain-external-arm-arm/Config.in:7
error: toolchain/toolchain-external/toolchain-external-arm-arm/Config.in: patch does not apply
Patch failed at 0001 support/kconfig: reference environment variables directly (remove 'option env=')

@Titouan (or Peter) could you please send a new version?

It'd be also great if you address concerns raised by Peter and Yann.

Kind regards,
Petr
