4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rob Landley <rob@xxxxxxxxxxx>
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.
