The problem is introduced by this patch:

http://sources.redhat.com/ml/binutils/2000-11/msg00246.html

In linking.o from libobjc, there are

Relocation section '.rela.sbss' at offset 0x3938 contains 2 entries:
  Offset    Info  Type            Symbol's Value  Symbol's Name          Addend
  00000000  1a00000002 R_ALPHA_REFQUAD       0000000000000000
__objc_class_name_Object  + 0
  00000008  1b00000002 R_ALPHA_REFQUAD       0000000000000000
__objc_class_name_NXConst + 0

and

  8 .sbss         00000010  0000000000000000  0000000000000000  00002820  2**3
                  ALLOC, RELOC

There is no SEC_LOAD on .sbss. But .rela.sbss has to have SEC_LOAD.
Otherwise, you will get that error. Richard's patch fixed debugging
sections, but brake the linker. I will check in my patch if I don't
hear any objections soon.
