The dsdt.asl is usually combined out of several files that are included in the main one. Whenever we change the content of any of such files, build system is not able to recognize them. Hence the easiest way is to force DSDT rebuild each time we run make.

The build process that you describe is not in our documentation.
By which defconfig is $(src)/dsdt.asl consumed? Where does it come from? Please, provide a reproducible example.
Would you be able to provide a documentation patch explaining how to use a user provided dsdt.asl file?
Best regards

I agree that this patch is better than having the bug. But yes the docs could really use some notes here, for the person who does come along and clean up the dependency bug.
Regards, Simon
The patch is neither applicable to origin/next nor to origin/master.
I only find a line
$(obj)/dsdt_generated.c: $(src)/dsdt.asl
Best regards
