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. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@32553 3c298f89-4303-0410-b956-a3cf2f4a3e73
