Description of problem:
In the course of 2.0 QA I found if you enabled CYGPKG_IO_SERIAL_DEVICES causing
the serial DDs to be linked in while debugging via serial, then any test "dies"
straight after startup, i.e. presumably because the diag output stops working.
Version-Release number of selected component (if applicable):
2.0, with 2.0 redboot.
