Perhaps the build itself has been changed to target ARMv6 ? Starting with ARMv7, dmb should be there. For ARMv6 support (and less), the Linux kernel provides a vDSO page implementing __kuser_memory_barrier. If you really need to build for ARMv6, this might be something to look into. I guess we'll need more information about your build target.
