	PR lto/83452
	* simple-object-elf.c (simple_object_elf_copy_lto_debug_section):
	Do not use UNDEF locals for removed symbols but instead just
	define them in the first prevailing section and with no name.
	Use the same gnu_lto_v1 name for all removed globals we promote to
	WEAK UNDEFs so hpux can use a stub to provide this symbol.  Clear
	sh_info and sh_link in removed sections.
