New description:

 Test runs with a interrupt driven console driver result in unreliable test
 outcomes.

 Problem was noticed with test runs on Microzed, for example
 libtest/block08:

 The test prints:
 {{{
 ** END OF TEST BLOCK 8 ***
 }}}

 The `rtems-test` command marks the result as a failure. There is a single
 `*` missing from the start of the line. I attach the full test trace.

Comment (by Sebastian Huber):

 If we use BSP_output_char for all tests, then the console driver is not
 tested. We probably need a special test for it.

 We should also remove CONFIGURE_APPLICATION_NEEDS_CONSOLE_DRIVER from all
 other tests.
