The mail was about two unrelated problems:

(1) GDB by default fails to build on some archs of AIX.
    This could be fixed.  Currently I do not know how but there is some way.

(2) The ppc sim target is useless.  Therefore it wastes time of people trying
    to use it.

By fixing (2) one also fixes (1) as a side effect.  Fixing just (2) on its own
makes sense.

The patch below is to fix (2).
