Noob Hello World sparc/leon2 console not working

I just installed RTEMS 4.6.5 and am trying to run the example Hello
World on a Sparc/Leon2 board.  The problem is there is no console
output, the program hangs.  Is there a compile option/define/or anything
I need to set in order to get console output?  The makefile includes

Following is the output from the compile and gdb.

% make
test -d o-optimize || mkdir o-optimize
sparc-rtems-gcc --pipe -B/opt/rtems/sparc-rtems/leon2/lib/ -specs
bsp_specs -qrtems   -g -Wall  -O2 -g     -mcpu=cypress -msoft-float
-c   -o o-optimize/test.o test.c
sparc-rtems-gcc --pipe -B/opt/rtems/sparc-rtems/leon2/lib/ -specs
bsp_specs -qrtems   -g -Wall  -O2 -g     -mcpu=cypress -msoft-float
-o o-optimize/hello.exe
o-optimize/test.o   /opt/rtems/sparc-rtems/leon2/lib/no-dpmem.rel

  92368    2868    4956  100192   18760 o-optimize/hello.exe

% sparc-rtems-objcopy -O srec o-optimize/hello.exe o-optimize/hello.srec

I then run GRMON, target it with gdb and load the srec.  The program
hangs, so I kill it and produce this output:

Program received signal SIGINT, Interrupt.

I've also used GRMON to step through the assembly and it looks like the
offending function is rtems_io_register_name() -> mknod(), but that's as
far as I've gotten, and I figured there must be something simple I'm
missing.  Any assistance would be greatly appreciated.
