nommu: ptrace support
The patch below adds ARM ptrace functions to get the process load address.
This is required for useful userspace debugging on mmuless systems. These
values are obtained by reading magic offsets with PTRACE_PEEKUSR, as on other
nommu targets. I picked arbitrary large values for the offsets.
