    elf: Issue la_symbind for bind-now (BZ #23734)
    
    The audit symbind callback is not called for binaries built with
    -Wl,-z,now or when LD_BIND_NOW=1 is used, nor the PLT tracking callbacks
    (plt_enter and plt_exit) since this would change the expected
    program semantics (where no PLT is expected) and would have performance
    implications (such as for BZ#15533).
    
    LAV_CURRENT is also bumped to indicate the audit ABI change (where
    la_symbind flags are set by the loader to indicate no possible PLT
    trace).
    
    To handle powerpc64 ELFv1 function descriptor, _dl_audit_symbind
    requires to know whether bind-now is used so the symbol value is
    updated to function text segment instead of the OPD (for lazy binding
    this is done by PPC64_LOAD_FUNCPTR on _dl_runtime_resolve).
    
    Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
    powerpc64-linux-gnu.
