This patch fixes the lookup_dcookie for the MIPS o32 ABI. Although I
only tested with little-endian, the big-endian case needed fixing as
well but is untested (but what are the chances that this is not the
correct fix?).
This is the only patch I needed to get the user space oprofile
programs to work for mipsel-linux.
I am CCing the linux-mips list as this may be of interest there as well.

and little endian.
