Ok it could be problem with binutils/gcc. But in general this problem will occurs if size of data and bss section is big enough, so gp can not be set on proper place. If we have large project (mixed c and c++, linked with libstdc++, libsupc++) and if we compiled project source with -mlong-calls and -G0 in this case problem with MIPS_GPREL_16 only occurs on functions from gcc library (libstdc++, liblsupc++), because this libraries are not compiled with -mlong-calls and -G0?
If my conclusion is correct, is it possible to rebuild this libraries with -mlong-calls and -G0 option?

Without a testcase I'm not certain what's happening, but we've fixed a number of problems with such over the years.
