Build mips kernels with -G 0, to disable use of so-called `small' data and
bss sections. The current kernel linker script is not gp-friendly enough for
that; and while gas 2.15 was not attempting to output gp-relative relocations
for variables which might have ended up in .sdata or .sbss, gas 2.17 will,
and the kernel will fail to link.
To be improved eventually with a better kernel ld script putting the
gp-addressable sections close enough to gp... and making sure kernel gp is
reloaded in all the userland->kernel code paths which might need gp in the
kernel.
