You are using the native UNIX gcc and synthesized unix port.  
When you use the "synthesized" UNIX port you are actually native so
everything
eventually boils down to a native Linux call.  Even the system call
support
in RTEMS is not used.

And you are not using it.  You have to configure as --target=i386-rtems
and --enable-rtemsbsp=pc386.  Then you have to boot the RTEMS
application.
