kernel: fix ccache variable sanitation for clang builds * When using "?=", expansion doesn't happen right away, so the ccache variable is sanitized before KERNEL_CC gets expanded and no ccache is ever used for clang builds. * With ":=", expansion happens immediately. So let's manually check if KERNEL_CC is already set somewhere else to determine whether or not we should set it ourselves using ":=". Change-Id: I8a61767606a4f3d4c6ba88c68b10fd2e11783406
