Did not have this problem before. I pulled the latests changes and run
./bootstrap -p and ./boostrap, and I was able to build the new BSP.

Sure I second this opinion.

I remember I sent Chris an old patch to do so, but I think he may be
too busy to check it. If it has any problems, I will sumbit a new one.

Depends where do you configured/built it. It's called or32-elf-sim
(from old last release?) and sim from github, or vise versa.

I run the following command:
"or32-elf-sim -f ~/sim.cfg $PATH_TO_EXE"

where ~/sim.cfg is in my home, it's also here (should I add it to
RTEMS and if yes where?)
https://github.com/heshamelmatary/or1k-rtems/blob/master/sim.cfg

And it should wait for gdb to remotely connect at port 50001

I will fixup the other issues and submit the patch. I am just a little
busy with debugging the printf issue these days :)
