PR22220, BFD linker wrongly marks symbols as PREVAILING_DEF_IRONLY

non_ir_ref_dynamic wasn't being set in the case where we have a
versioned dynamic symbol definition with a non-versioned matching IR
symbol.

bfd/
	PR 22220
	* elflink.c (_bfd_elf_merge_symbol): Set non_ir_ref_dynamic in
	a case where plugin_notice isn't called.
ld/
	* testsuite/ld-plugin/pr22220.h,
	* testsuite/ld-plugin/pr22220lib.cc,
	* testsuite/ld-plugin/pr22220lib.ver,
	* testsuite/ld-plugin/pr22220main.cc: New test.
	* testsuite/ld-plugin/lto.exp: Run it.
