Subject: build: toplevel.mk: fix missing kconfig dependency tracking
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=418dc0497db02b1ccddf26009e16d42496b7f554;p=openwrt%2Fstaging%2Fynezz.git

build: toplevel.mk: fix missing kconfig dependency tracking

Toplevel Make is not aware about changes in the `scripts/config/*conf`
targets and this is causing issues for during update to that part of
build tree, where one needs to handle this manually by either force
rebuilding the targets or running `make config-clean`. Fix this by
forcing the rebuild if necessary.

Fixes: #9297
