iostreams test failure on psim

[Till Straumann]

Weird. It works for me here on psim but I might use a different
4.9 snapshot (and different gcc/newlib patches).

It probably fails creating the __mutex

(e.g., rtems_gxx_mutex_init() panics if semaphore
creation fails -- do you have enough configured?).
