rtems-examples posix_api does not work with simulators/emulators like qemu and sis

In rtems-examples/posix_api the examples

psx_example_[123] do not work as they should (especially timing).

E.g. in psx_example_1 the sleep(1) is ignored by sparc-rtems6-sis -rt … .
With qemu-system-arm -M xilinx-zynq-a9 the "sleep" at least works.

With both simulators/emulators psx_example_2 gets stuck ( probably in pthread_join (child, NULL) ).

BTW: in this example pthread_cond_timedwait() return “1” !. In the documentation one can find
Should return “0” if ok, EINVAL or ETIMDOUT on failure.

psx_example_3 works, but timing is totally ignored.
