commit a298bbab903e3fb4cbe16d36d6195e68fad1b776 upstream.
When cross compiling the kernel with clang, we need to override CLANG_CROSS_FLAGS when preparing the step libraries.
Prior to commit d1d096312176 ("tools: fix annoying "mkdir -p ..." logs when building tools in parallel"), MAKEFLAGS would have been set to a value that wouldn't set a value for CLANG_CROSS_FLAGS, hiding the fact that we weren't properly overriding it.
