testing uclibc changes is tricky because the final gcc tends to miscompile
uclibc code or barf up internal compiler errors.
install binutils into $(TOOLCHAIN_DIR)/initial (without changing the configure
prefix) and copy it from there to $(TOOLCHAIN_DIR)/ so that the initial gcc
can be put into $(PATH) for the uclibc build, even if the final gcc
is already installed.
