No. Like the error says, you only need it if you modify the makefile templates or other configuration files. If the build is trying to use automake, it suggests you've touched those files so that the timestamps make them look like they've been modified. There's a script you can use to update timestamps of generated files so they no logner appear to be out of date. In the GCC source tree run 'contrib/gcc_update --touch' That should allow you to build without needing automake.
