[PATCH 5/5] ld: Ignore the new weak definition if needed

[H.J. Lu]

Ignore the new weak definition if the old definition comes from the LTO
IR object since plugin_notice will turn it into undefweak.

	PR ld/26262
	* elflink.c (_bfd_elf_merge_symbol): Ignore the new weak
	definition if the old definition comes from the LTO IR object.
