Don't complain undefined weak dynamic reference When undefined non-weak references in IR objects are optimized out by LTO, we can have weak dynamic referencs to symbols marked with bfd_link_hash_undefined. We shouldn't complain such undefined weak dynamic references. bfd/ PR ld/24486 * elflink.c (elf_link_output_extsym): Don't complain undefined weak dynamic reference. ld/ PR ld/24486 * testsuite/ld-plugin/lto.exp: Run PR ld/24486 tests. * testsuite/ld-plugin/pr24486a.c: New file. * testsuite/ld-plugin/pr24486b.c: Likewise. * testsuite/ld-plugin/pr24486c.c: Likewise. 2019-04-26 22:52:00 +08:00			`extern int FLAGS_verbose;`
