| Subject: x86/boot: Use CROSS_COMPILE prefix for readelf |
| |
| From: Rob Landley <rob@landley.net> |
| |
| 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. |
