4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Rob Landley <[email protected]> commit 3780578761921f094179c6289072a74b2228c602 upstream. The boot code Makefile contains a straight 'readelf' invocation. This causes build warnings in cross compile environments, when there is no unprefixed readelf accessible via $PATH. Add the missing $(CROSS_COMPILE) prefix.
