* elflink.h (elf_adjust_dynamic_symbol): Copy REF_REGULAR_NONWEAK
and NON_GOT_REF from weak defined symbol to real symbol.
* elf32-i386.c (elf_i386_check_relocs): Set NON_GOT_REF.
(elf_i386_adjust_dynamic_symbol): If NON_GOT_REF is not set, don't
create a COPY reloc.
* elf32-sparc.c (elf32_sparc_check_relocs): Set NON_GOT_REF.
(elf32_sparc_adjust_dynamic_symbol): If NON_GOT_REF is not set,
don't create a COPY reloc.
