Things would be much simpler is all tools were adjusted to:
a) the subdir they live in is the make target name
b) each tool has three mandatory targets:
1) default target => build the tool
2) clean
3) install

I can see that with the layout today you cannot
distingush between the various targets below power.
But the current solutions is not scaleable nor maintainable.

Even if you cannot fix power/* then testing looks easy.

But all that can always to improved and consolidated later.
