Build tools like OpenEmbedded set the CFLAGS environment variable to be in line with distro-wide decisions. Updating OpenEmbedded-core to point at the new mmc-utils breaks, because VERSION would then be undefined. Instead of having users workaround this by feeding in -DVERSION from the outside, let's just move it out of environment-overridable CFLAGS and into AM_CFLAGS instead. This will inconvenience users that set their own VERSION a bit: The Makefile sets -Werror and specifying -DVERSION twice will trigger it because of the duplicate definition. This can be resolved by specifying -UVERSION first. Given that the VERSION macro has only been there for a month, this is deemed acceptable.
