Upstream solution in kernel has been merged [1] and will be part of kernel 4.21
(kbuild updates for 4.20 has been merged day before).
Would you like to backport it to buildroot + add necessary applications (setting
the variable?) or shell I do it?

I also have plans to upgrade our kconfig to 4.19 + review the patches (some of
them might can be adjusted to be suitable for upstream, so we'd be able to get
rid of them).
