__wrap_shm_open only works if you have the CONFIG_XENO_OPT_POSIX_SHM
option enabled. Is it enabled? Note that xenomai posix skin shm support
is mainly useful for sharing memory between kernel and user-space. If it
is enabled, then please tell us what is the value of errno when
__wrap_shm_open fails.
