 -  Filtering the tools available from the host's ``PATH`` to only a specific set
    of tools, set using the :term:`HOSTTOOLS` variable.
 
-.. note::
-
-   Because of an open bug in GCC, using ``DISTRO_FEATURES:append = " lto"`` or
-   adding ``-flto`` (Link Time Optimization) to :term:`CFLAGS` makes the resulting
-   binary non-reproducible, in that it depends on the full absolute build path
-   to ``recipe-sysroot-native``, so installing the Yocto Project in a different
-   directory results in a different binary.
