 DJ> Eh, no.  This patch would turn on software single-step for GNU/Linux

This patch simply removes the macro definitions.  It does _not_ turn
on software single step for GNU/Linux since the macro tests for the
gdbarch vector which is NULL because it is undefined, but it is
defined for AIX.

I have verified this by both watching it with gdb and with strace
output.

 DJ>  also I doubt that's what you wanted to do.

You are right in that it is not what I wanted when this whole thing
started, but it was suggested that I remove the macro before I propose
the ability to select SW over HW at runtime.
