The pthreads functions are integral part of RTEMS and Newlib
so you do not need to link other than usual libraries to
have complete ptherads support on RTEMS.

The default libraries list is hidden under 

  -specs bsp_specs -qrtems

GCC options. Maps to

  -lrtemsbsp -lrtemscpu  -latomic -lc -lgcc

These libraries contains all implemented pthread_* functions as
well as nanonesleep and other functions included in -lrt under Linux.

You may need to add -lm explicitly if floating-point is used.

Best wishes,
