This should be fixed with https://patchwork.ozlabs.org/patch/1268895/.
Tell me if it does not work.

I have a hunch that for buildbot the "treat recursive dependencies as warnings instead of errors" option (from 3204430e3 ) should be activated in the config binary, or alternatively some major work for re-organising the mac80211 submodule dependencies needs to be done.

Yes, I've added the WARN_RECURSIVE_DEP option to be used by the bots.
I wasn't sure if this option should be default or not.  My reasoning
was that erroring out would make it harder for new circular
dependencies to creep in, and bots could run with it on.
Clean the scripts/config directory with make config-clean (if bots
don't start with a clean slate), then add  WARN_RECURSIVE_DEP=1 to the
bots make flags.

Most of the time, the recursive dependencies reported by config the
ones causing the trouble.  It usually occur because some package
selects (DEPENDS= +<pkg>) another package that depends on another
symbol without either selecting the symbol (DEPENDS=+<sym> +<pkg>)  or
only selecting the package if symbol is on (DEPENDS=+<sym>:<pgk>).
The most common case is a package selecting a module that depends on
some global feature.  The ones I've fixed in 2e6b6f9fca ("kernel: add
@IPV6 dependency to ipv6 modules") had kmod packages selecting ipv6
modules without checking if CONFIG_IPV6 is enabled or not.
