PR27311, ld.bfd (symbol from plugin): undefined reference
A default versioned symbol definition in a shared library is overridden by an unversioned definition in a regular object file, and thus should not be reason to make an as-needed library needed. bfd/ PR 27311 * elflink.c (_bfd_elf_add_default_symbol): Add override parameter. Use when handling default versioned symbol. Rename existing override variable to nondef_override and use for non-default versioned symbol. (elf_link_add_object_symbols): Adjust call to suit. Don't pull in as-needed libraries when override is set. ld/ * testsuite/ld-plugin/pr27311.d, * testsuite/ld-plugin/pr27311.ver, * testsuite/ld-plugin/pr27311a.c, * testsuite/ld-plugin/pr27311b.c, * testsuite/ld-plugin/pr27311c.c: New testcase. * testsuite/ld-plugin/lto.exp: Run it. Correct PR14918 and PR12982 entries.
