1e73427f66 tools/counter: add a flexible watch events tool
This adds a new counter tool to be able to test various watch events.
A flexible watch array can be populated from command line, each field
may be tuned with a dedicated command line sub-option in "--watch" string.
Several watch events can be defined, each can have specific watch options,
by using "--watch <watch 1 options> --watch <watch 2 options>".
Watch options is a comma separated list.

It also comes with a simple default watch (to monitor overflow/underflow
events), used when no watch parameters are provided. It's equivalent to:
counter_watch_events -w comp_count,scope_count,evt_ovf_udf

The print_usage() routine proposes another example, from the command line,
which generates a 2 elements watch array, to monitor:
- overflow underflow events
- capture events, on channel 3, that reads read captured data by
  specifying the component id (capture3_component_id being 7 here).

aead78125a tools/counter: Makefile: Replace rmdir by rm to avoid make,clean failure
Use rm -df instead of rmdir -p since rmdir requires the directory exist
so it causes "make -C tools clean" failed if someone only builds other
tools but not counter.

228354ed69 tools/counter: Makefile: Remove lingering 'include' directories on make clean
`make` creates 'include' directories where necessary, so remove them as
appropriate on `make clean`.

5c8166419a kbuild: replace $(if A,A,B) with $(or A,B)
$(or ...) is available since GNU Make 3.81, and useful to shorten the
code in some places.

Covert as follows:

  $(if A,A,B)  -->  $(or A,B)

This patch also converts:

  $(if A, A, B) --> $(or A, B)

Strictly speaking, the latter is not an equivalent conversion because
GNU Make keeps spaces after commas; if A is not empty, $(if A, A, B)
expands to " A", while $(or A, B) expands to "A".

Anyway, preceding spaces are not significant in the code hunks I touched.
