H.J. Lu 37a9e49a28 Properly handle common symbol and weak function 
bfd/

	PR ld/14591
	* elf-bfd.h (_bfd_elf_merge_symbol): Add an argument to return
	if the old symbol is weak.

	* elf32-sh-symbian.c (sh_symbian_relocate_section): Update
	_bfd_elf_merge_symbol call.

	* elflink.c (_bfd_elf_merge_symbol): Add an argument to return
	if the old symbol is weak.
	(_bfd_elf_add_default_symbol): Update _bfd_elf_merge_symbol
	call.
	(elf_link_add_object_symbols): Don't update symbol type from a
	weak definition.  Update symbol type from a common symbol when
	overriding a weak symbol.
