I am still confused; from my perspective it appears that some 
of the RTEMS applications, for example netdemo, appear to 
explicitly reference librtemscpu.a?

Making all in netdemo
make[1]: Entering directory `/home/hill/nios2-rtems/rtems/rtems-git/network-demos/netdemo'
make[1]: *** No rule to make target 
`/home/hill/install/rtems-4.11-/nios2-rtems/altera-sys-config/lib/librtemscpu.a',
 needed by `o-optimize/netdemo.exe'.  Stop.

Thanks for your assistance,

Jeff
