gcc: split up the build process into three distinct stages (minimal, initial, final), to clean up the dependency handling nastiness and to improve support for rebuilding parts of the toolchain SVN-Revision: 22319

toolchain: fix the sysroot mess by getting rid of $(TOOLCHAIN_DIR)/usr and moving it back to $(TOOLCHAIN_DIR), this change makes the toolchain relocatable again, which should fix the SDK SVN-Revision: 22723

toolchain: keep the initial gcc around for later uclibc rebuilds 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.
