A project I am working on for ia32, ia64 and x86-64 uses additional
bss sections.

BTW, the current elf.sc has

  ${RELOCATING+${OTHER_BSS_END_SYMBOLS}}
  ${RELOCATING+. = ALIGN(${ALIGNMENT});}
  ${LARGE_SECTIONS}

That means OTHER_BSS_END_SYMBOLS may be set before bss sections in
LARGE_SECTIONS. My patch changes it to

  ${OTHER_BSS_SECTIONS}
  ${RELOCATING+${OTHER_BSS_END_SYMBOLS}}
  ${RELOCATING+. = ALIGN(${ALIGNMENT});}
  ${LARGE_SECTIONS}

It doesn't have this problem.
