| OE needs to be able to change the default compiler. If we pass in HOSTCC |
| through the make command, it overwrites not only this setting but also the |
| setting in tools/Makefile wrapped in ifneq ($(CROSS_BUILD_TOOLS),) which |
| breaks the build. |
| |
| We therefore use override to ensure the value of HOSTCC is overwritten when |
| needed. |

| RP: Updated the patch to the version being submitted to upstream u-boot |
