Thanks! Almost good.
Just small nits.

'$(src)/streamline_config.pl' is better than '$(obj)/streamline_config.pl'
since it is a checked-in file.
'$(src)' and '$(obj)' are always the same.
(https://github.com/torvalds/linux/blob/master/scripts/Makefile.build#L6)
So, there is no effective difference.
It is just a coding convention to use $(obj)/ for generated files,
and $(src)/ for source files.
The original code already used $(obj)/, so this is not your fault
but I want to fix it while we are here.
One more nit.
$(obj)/conf $(silent) --silentoldconfig $(Kconfig);
can be
$< $(silent) --silentoldconfig $(Kconfig);
I guess you did not touch this line to avoid
conflict with my patch.
If you agree those two, shall I fix it up
when I apply it?
