+No -specs bsp_specs GCC Option
+------------------------------
+
+The ``-spec bsp_specs`` GCC Option is no longer needed to build RTEMS
+applications and there is no :file:`bsp_specs` file installed.  If you use this
+option, then you get an error like this:
+
+.. code-block:: none
+
+    sparc-rtems6-gcc: fatal error: cannot read spec file 'bsp_specs': No such file or directory
+
+You can remove this GCC option from your build to fix this error.
+Alternatively, you can add an empty :file:`bsp_specs` file.
