Construct short architecture name from architecture signature.
Map existing architecture signature to short architecture name at build time. This architecture name is (as yet) unused, but will be used to build per-architecture cache files with names made unique by including the architecture name. The auto-detected architecture name can be overridden with the --with-arch=ARCH configure option.
