Thanks. I got this twisted owing to the gdbserver using the host elf.h and me
keeping the binutils and GDB patches separate when I should have had the
elf/mips.h changes shared between the two.

I'll send an updated patch with the #ifdefs removed and ensure that binutils
commit precedes the GDB commit when approved.
