I prefer changing only one line:



diff --git a/scripts/kconfig/Makefile b/scripts/kconfig/Makefile
index 0b1d15efaeb0..af1c96198f49 100644
--- a/scripts/kconfig/Makefile

-cmd_conf_cfg = $< $(addprefix $(obj)/$*conf-, cflags libs bin)
+cmd_conf_cfg = $< $(addprefix $(obj)/$*conf-, cflags libs bin); touch

Also, please update .gitignore


diff --git a/scripts/kconfig/.gitignore b/scripts/kconfig/.gitignore

Thanks.
