--- Comment #2 from David Chisnall <csdavec at swan.ac.uk> ---
This looks like a bug in the input code.  The relocation is caused by this
inline assembly:

jal   __do_global_dtors_aux

This is wrong for PIC, it should be:

    dla  $t9, __do_global_dtors_aux
    jalr $t9

The assembly is instantiated from the macro CRT_CALL_STATIC_FUNCTION.  This
appears to come from contrib/gcc/config/mips/mips.h, which contains some
wonderful things like '/* Switch to #elif when we're no longer limited by K&R
C.  */' and, though it does have O32 and N64 / N32 variants, it doesn't appear
to be have a PIC variant.

This code is sufficiently horrible that the correct fix probably involves
napalm.
