'python import rtems' fails in gdb

[Ric Claus]

When following ​https://devel.rtems.org/wiki/Developer/Tools/RTEMS_GDB_Python I got:

(gdb) python import rtems
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/home/claus/development/rtems/4.11/share/gdb/python/rtems/__init__.py", line 31, in <module>
  File "/home/claus/development/rtems/4.11/share/gdb/python/rtems/rtems.py", line 38, in <module>
  File "/home/claus/development/rtems/4.11/share/gdb/python/rtems/threads.py", line 39, in <module>
ImportError: No module named rbtrees
Error while executing Python code.
(gdb)

rbtrees.py is in the tree, so I modified the rtems-source-builder/rtems/sources/git/rtems-tools.git/tools/gdb/python/wscript to include this and two other missing .py files (mutex.py and time.py). I didn't figure out how to apply my change as the file just reverted when I tried. Attached is an untested patch.

Any chance we could get this in RSB 4.11.0-rc2, Chris?

[Chris Johns]

It should be made to work.
