RTEMS includes all system calls in a single library in 4.5.0.
If you use the normal linking arguments, they are just there.  
No extra libraries.  They are in librtemsall.a.

Did you compile using i386-rtems or native gcc?  Even though you are
on the same hardware, RTEMS still views it as an embedded system and
you will have to "boot RTEMS"
