Allow ARC target to be configured with --with-cpu=<cpu-name>.
gas * config.in (TARGET_WITH_CPU): Undefine. * configure.ac: Add --with-cpu support, and define in config.h. * configure: Regenerate. * config/tc-arc.c: Use TARGET_WITH_CPU to select default CPU. * NEWS: Mention new configure option.

* Add --with-cpu=TYPE configure option for ARC gas. This allows the default
