The toolchain wrapper will be reused for the internal toolchain, so it belongs in the toolchain directory. Also, the ext- prefix is removed from it. The build commands are moved to a new toolchain-wrapper.mk. The wrapper arguments that are also relevant for the internal toolchain wrapper are moved to toolchain-wrapper.mk, the rest stays in toolchain-external.mk. While we're at it, move the building of the toolchain wrapper to the build step of toolchain-external. There is no specific reason to do this, other than that it fits better semantically. Also remove the MESSAGE call, otherwise we'd see: >>> toolchain-external undefined Building >>> toolchain-external undefined Building toolchain wrapper /usr/bin/gcc ... Having an extra "Building toolchain wrapper' message is pointless. The useless condition on $(BR2_TARGET_OPTIMIZATION) is removed. It was always true because it wasn't qstrip'ped first, so clearly it works without that condition as well. Also rewrapped some comments and removed the 'external' reference.
