You should specify which version of binutils you are using. This
might have been a bug in an old version which is now fixed.
You should also specify how you configured gcc and binutils and what
command line you are using to build your binaries. Possibly the
problem is with how the tools were built or invoked.

The .gptab seems to only be supported in the big-endian targeted
versions of the mips linker. Compare ld/emulparams/elf32bmip.sh with
ld/emulparams/elf32lmip.sh for a demonstration of this.
So, either build binaries for a big endian mips, or copy the
OTHER_SECTIONS definition from elf32bmip.sh to elf32lmip.sh and rebuild
the linker.
