 If I used the same prefix as an bare metal ELF tool chain could gcc pick
 up that assembler?

 Do we need more or better documentation on the `$prefix` in the User
 manual?

 > 2. Some header and other files of the existing installation may be used
 instead of the one from the current sources.

 Why is gcc doing this? It seems wrong and dangerous.

 > 3. The installation adds only files, it does not remove obsolete files
 leaving a mixture of old and new files in the prefix.

 The binutils and gcc do just this as well. The RSB is not a packaging or
 deployment tool. That is a role I see existing outside of the RTEMS
 project where specialisation and support can happen.

 > 4. The Ada installation stops with permission errors.

 I thought this was in the Ada build when run from python?

 > 5. In case something goes wrong it is not easy to figure out that the
 reason is an existing installation that interfered.

 Agreed, but why is it the role of the RSB tool (not the configuration
 parts) to deal with this?

 I have offered a solution and I am willing to review patches.
