Makefile: Add a 'checkthumb' rule
This rule confirms that if we're on ARM and we have enabled THUMB builds
that we have a new enough toolchain to produce a working binary.
Changes in v2:
- Switch to ALL-$(CONFIG_SYS_THUMB_BUILD) in arch/arm/config.mk (Mike F)
- Simplfy checkthumb test after doing the above
