+Upstream-Status: Inappropriate  [OE-Specific]
+
+When building emacs, it builds some tools for the HOST
+that are then used to build for target, such as
+make-fingerprint and make-docfile and bootstrap-emacs,
+this needs to be adapted to be used by bitbake, otherwise
+the compiled executables arent compatible with the HOST.
+
+We also need to be able to use emacs env variables to
+control how bootstrap-emacs is used when cross-compiling.
+
+Use the above mentioned tools provided by the native
+version of the recipe instead.
