It's a bug bug in ld, one in BFD and a sillyness in IRIX ELF which the linker
uses.  IRIX ELF uses different sorting rules for the symbol table, see
mips_elf_sym_is_global in bfd/elf32-mips.c.

 - Bug one: ld generated output should follow the same rules as assembler
   generated output.
 - Bug two is more a design flaw - why does Linux/MIPS and most other
   MIPS ELF configurations use IRIX and not ABI ELF?
 - Bug three is that mips_elf_sym_is_global applies these IRIX ELF sorting
   rules even to ABI ELF.
