And already a question regarding the new branch: You cleaned up the 
rtems-bsd-kernel-namespace.h (which is great).

My patch removes some duplicated functions that are in RTEMS and in 
libbsd. The ones in RTEMS are definitively the correct ones and the ones 
in libbsd return wrong values sometimes. With your patch, the functions 
are now in the namespace header (which is OK).

I tried to regenerate the header using the rtems-kern-symbols. But even 
with the --regenerate option like described in the CONTRIBUTING.md, the 
symbols are not removed. I can remove them manually and the 
rtems-kern-symbols script doesn't change the header if I re-run it. So 
I'm quite sure that this is an OK solution. But it somehow feels wrong 
to manually change a generated header. Is there something I used wrong?

What I did:

- Re-build libbsd and note that the tests don't link any more.

- run `./rtems-kern-symbols --regenerate --rtems-tools=<path_to_tools>`
   Nothing has been changed.

- manually remove the symbols

- re-build (now successfully)

- run `./rtems-kern-symbols --regenerate --rtems-tools=<path_to_tools>`
   Nothing has been changed. Symbols are still removed.

- add symbols manually again

- run `./rtems-kern-symbols --regenerate --rtems-tools=<path_to_tools>`
   Nothing has been changed. Symbols are still there.

So I think my core question is: Does the tool clean up old symbols or do 
I have to do that manually?

Best regards

Christian
