    gold: Always resolve non-default weak undefined to 0

    Non-default weak undefined symbols in executable and shared library are
    always resolved to 0 at runtime and don't need dynamic relocation.

    Tested on i686, x86-64, powerpc64le and aarch64.

            PR gold/32071
            * symtab.cc (Symbol::final_value_is_known): Always resolve
            non-default weak undefined symbol in executable and shared library
            to 0 at runtime.
            * symtab.h (Symbol::needs_dynamic_reloc): Return false for
            non-default weak undefined symbol in executable and shared library.
            * testsuite/Makefile.am: Add weak_undef_test_3 and
            weak_undef_test_4 tests.
