multiple definition of __getreent (in newlib's crt0.c and RTEMS' confdefs.h)

[Sebastian Huber]

Hello,

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
