This drops the `.cpu` directive from the ARM gchelper_*.s files. Having this directive breaks the linker when targeting older CPUs (e.g. `-mthumb -mthumb-interwork` for `-mcpu=arm7tdmi`). The actual target CPU should be determined by the compiler options. The exact CPU doesn't actually matter, but rather the supported assembly instruction set. So the files are renamed to *_thumb1.s and *thumb2.s to indicate the instruction set support instead of the CPU support. Signed-off-by: David Lechner <david@pybricks.com>
