 -  Filtering the tools available from the host's ``PATH`` to only a specific set
    of tools, set using the :term:`HOSTTOOLS` variable.

+   Because of an open bug in GCC, using ``DISTRO_FEATURES_append = " lto"`` or
+   adding ``-flto`` (Link Time Optimization) to ``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.

 Can we prove the project is reproducible?
