I'm about to commit this to fix the problems introduced by the new
reference counting scheme.

2001-10-15  Alan Modra  <amodra@bigpond.net.au>
	    H.J. Lu  <hjl@gnu.org>

	* elf32-hppa.c (elf32_hppa_copy_indirect_symbol): Merge dyn_reloc
	counts for aliases instead of aborting.
	* elf32-i386.c (elf_i386_copy_indirect_symbol): Likewise.
	* elf64-ppc.c (ppc64_elf_copy_indirect_symbol): Likewise.

	* elf32-hppa.c (elf32_hppa_adjust_dynamic_symbol): Set plt.offset
	to -1 for non-function symbols.
	* elf32-ppc.c (ppc_elf_adjust_dynamic_symbol): Likewise.
	* elf32-s390.c (elf_s390_adjust_dynamic_symbol): Likewise.
	* elf64-ppc.c (ppc64_elf_adjust_dynamic_symbol): Likewise.
	* elf64-s390.c (elf_s390_adjust_dynamic_symbol): Likewise.
	* elf64-x86-64.c (elf64_x86_64_adjust_dynamic_symbol): Likewise.
	* elf32-i386.c (elf_i386_adjust_dynamic_symbol): Refer to
	plt.offset instead of plt.refcount when setting to -1.
