Hi Brady,

This is fixed in the current CVS version of binutils.  I have no idea
what version of ld you are running, but if you look at the function
_bfd_mips_elf_merge_private_bfd_data in elf32-mips.c you'll see that
the check ibfd->xvec->byteorder != BFD_ENDIAN_UNKOWN is forgotten in
the if statement.
