Several of the test makefiles did not have this.
For this I've patched at least:
src/tools/Makefile-server.am
src/tracing/Makefile.am
src/erasure-code/Makefile.am
src/rgw/Makefile.am

And this is indeed what I've added ATM to get my tests compiled.
But I really wonder if this is the way to go, instead of fixing it
in configure and be done with it. Just like wiht most of the other
libraries that are setup thru automake/configure. That would also
help other ports,  then for that port one does not have to augment
again all locations.

AND if new tests would be written, we do not have to check if all
exempts are correctly covered.
