* tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.

Rich and I believe the "real problem" was that both single_step
and target_resume were issuing PT_CONTINUE calls.  This would
cause the second PT_CONTINUE to sometimes fail because the process
was already running.
* infptrace.c (child_resume):  Remove AIX_BUGGY_PTRACE_CALL kludge.
