Subject: u-boot-fw-utils: follow the compile fixes for native/cross used in
 oe-core

The U-Boot Makefile has a unusual way of compiling the user space tools which
results in the wrong toolchain (native vs. target) being used.
Drop our downstream fix in favour of how openembedded-core does this now.

+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
