Hi,

In my projects that use Automake and the "parallel" test driver, often
I have 1000 unit tests, of which 100-150 are skipped and 1-5 fail.
When analyzing the "make check" results, the generated test-suite.log
is more handy to use than the 1000 different <test>.log files. However,
before I get an overview of the results, I have to eliminate the logs
of the SKIPped tests (because the 1-5 failures are intermixed with
the 100-150 SKIPped test logs). This is a process that takes 1-2 minutes
each time.

I could write a script that post-processes the test-suite.log to eliminate
them. But it is better if the logs of the SKIPped tests wouldn't appear
in the file in the first place. The SKIPped tests are uninteresting
in my case.

Here is a patch that allows the package maintainer to eliminate the
SKIPped test logs, thus making test-suite.log more useful: either
by running
  make check IGNORE_SKIPPED_LOGS=1
or by defining in the Makefile (or Makefile.am):
  IGNORE_SKIPPED_LOGS = 1

It includes a unit test, documentation updates, and passes "make check".
