While trying to migrate the u-boot support for our machine from oe-classic i hit a problem with this patch. :(

The

  EXTRA_OEMAKE = 'CROSS_COMPILE=${TARGET_PREFIX} CC="${TARGET_PREFIX}gcc ${TOOLCHAIN_OPTIONS}"'

in u-boot.inc leads to compiling problems with some build support tools. The tools (e.g. bmp_logo) are now compiled with the target compiler (arm-oe-linux-gnueabi-gcc in our case) instead of the host compiler. This results in build errors like

| ./bmp_logo logos/denx.bmp >/pm/sledz/oe-core/build/tmp-eglibc/work/hipox-oe-linux-gnueabi/u-boot-v2009.03+git91+e60beb13cf0135dc71c541021487b5ccc4d269cb-r8/git/include/bmp_logo.h
| /bin/sh: ./bmp_logo: cannot execute binary file

Reverting to

  EXTRA_OEMAKE = 'CROSS_COMPILE=${TARGET_PREFIX}'

seems to fix this problem.
