    lto/114655 - -flto=3D4 at link time doesn't override -flto=3Dauto at co=
mpile
time

    The following adjusts -flto option processing in lto-wrapper to have
    link-time -flto override any compile time setting.

            PR lto/114655
            * lto-wrapper.cc (merge_flto_options): Add force argument.
            (merge_and_complain): Do not force here.
            (run_gcc): But here to make the link-time -flto option override
            any compile-time one.
