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.
