you found a nasty piece in the RTEMS Newlib/GCC configuration. Newlib provides a crt0.o file which contains a bunch of global symbols suitable enough to make the GCC link-time configure tests happy. This file must never be used for a real RTEMS application. The default startfile of GCC (which is this Newlib ctr0.o) must be overruled.  This is usually done be the bsp_specs.  See also
