linux: may fail to boot for binutils 2.29+ even without armv7m
Commit f13477b (linux: config.in: add comment for Arm Cortex-M) added a comment so that the user that the linux kernel may miscompile with binutils 2.29+, when the target is an armv7m CPU. However, the real trigger is a compilation in thumb2 mode, which happens to be the only option for armv7m CPUs. We can't know whether the kernel will be built in arm or thumb2 mode, though, because we do not have that information: it is only available in the Linux' .config file, which we don;t have access to at the time we run our menuconfig. So, relax the conditions under which the comment is made, so that it appears as soon as binutils are >= 2.29 (i.e. not 2.28, which is the oldest we support) for ARM CPUs.
