Use -dr instead of -d.  You should then find that:

...these insns have relocations against _gp_disp.  The linker will
turn _gp_disp into an offset from _gp.

I'm still not sure what it is you're trying to do though.  What is
your target system?  VR413x GNU/Linux?  Or something else?
(I'm saying this as a binutils@ rathern than crossgcc@ reader btw.)

The command line:

> mips-deb-linux-gcc  -msoft-float -mgp32 -g -O2 -mips3 -G 0  -DGDB_STUB
> -I. -I./include  -I./config/mips3/vr4131 -I./config/mips3 -nostdlib

> serial.o logtask.o log_output.o vasyslog.o t_perror.o strerror.o 
> kernel_cfg.o   libkernel.a   -lgcc

(in particular the vr4131_elf_gdb.ld bit) suggests that you're trying
to use a *-elf (bare-metal) linker script with a GNU/Linux compiler,
so I wasn't sure whether your target really was GNU/Linux or not.
