Hello Patrick!
Now I was able to trigger this issue, but it seems to be present only
sometimes. Calling make more times hides that issue, so it looks like
something broken in Kconfig dependency generator for Makefiles... Or
maybe something dependent on GNU make...
I played a bit with it and after changing following line in that patch
shell_cmd = { $(echo-cmd) $(cmd_$(1)); }
by
shell_cmd = { $(call echo-cmd,$(1)) $(cmd_$(1)); }
that issue disappeared. But because it triggered on my machine only
sometimes, I do not know if it finally fixes it.
Could you please try this change? And do you have reproducer how to
_always_ trigger it and not only sometimes?
