* elf-bfd.h (RELOC_FOR_GLOBAL_SYMBOL): No error on relocatable link.
(elf_discarded_section): Move..
* bfd-in.h: ..to here.

relocs against symbols from discarded sections.

sec, sym, h etc. for final link. Squash error messages for
relocatable link. Clear section contents for relocs against
symbols in discarded sections, and zero reloc. Remove existing
zero r_symndx code.
