Log Message:
	Enable ptrace support for MIPS but only for log_subcmds.
	It is not possible to change the syscall return value on MIPS
	so we cannot support full intercept mode.
	Another complication on MIPS is that if a system call is invoked
	via syscall(__NR_###), v0 holds __NR_O32_Linux and the real syscall
	is in the first arg (a0) and other args are shifted by one.
