I believe your Linux/MIPS patch is wrong. Please follow the examples in
linux/alpha, linux/i386 and linux/ppc. Basically, you have to include
config/tm-linux.h and config/nm-linux.h from the linux/mips header
files. But in order to do that, please make sure you do
#include <nm-linux.h>
#include <tm-linux.h>
not
#include "nm-linux.h"
#include "tm-linux.h"
Otherwise, you may not get the header files you want since mips has
both liltle and big endians. Once you have done that, your problem
should go away.
