sparc: Fix ptrace() detach.
Forever we had a PTRACE_SUNOS_DETACH which was unconditionally recognized, regardless of the personality of the process. Unfortunately, this value is what ended up in the GLIBC sys/ptrace.h header file on sparc as PTRACE_DETACH and PT_DETACH. So continue to recognize this old value. Luckily, it doesn't conflict with anything we actually care about. Signed-off-by: David S. Miller <davem@davemloft.net>
