It's deliberately to not add '-m 644' when install coresight test
shell scripts under the folder tests/shell/coresight/ so that we can
keep the executable permission for these scripts. On the other flip,
we set 644 mode for the scripts under tests/shell/lib/ so these
scripts will not be executed directly by perf test framework.

@Carsten, if have chance could you confirm for above change?

If you need for some .sh, coresight test's to have x set while all of
the others don't have, and you have a good reason for that, ok, we just
add a comment.

Simply to say, all lib scripts are not needed for execute permission.
Yes, it's good to add a comment for the installation steps.

I'll add it back when the first .sh gets added to tests/shell/coresight/

Sorry for introducing extra efforts for you and thanks!

This also has to go, I'll check and fix this loop that doesn't follow
the existing output style, happens with ´make install', etc too:

Ouch, if we can update the file tests/shell/coresight/Makefile as below:

$(CLEANDIRS):
$(call QUIET_CLEAN, test-$(@:clean-%=%)) $(Q)$(MAKE) -C $(@:clean-%=%) clean >/dev/null

I had to do it, so far, at the time that the above line is first added
as:

And for the normal build and install, somehow that $(Q) is not being
obeyed there, so I'm using straight @ for now so that we have a clean
output, someone more knowledgeable in the Makefile voodoo can then fix
it.

DOn't you want to prefix this with + too (to preserve jobserver, i.e. parallel builds)?

Re the Q -- is it exported? What is printed with echo $(Q).
