Makefile: ARMv7-M has no CPSR register
Compiling on ARMv7-M fails when trying to address the CPSR register which
is not available on this architecture.
Atomic functions refer to the CPSR register if compiled with
arch/arm/include/asm/proc-armv/system.h. On ARMv7-M we should hence
use arch/arm/thumb1/include/asm/proc-armv/system.h instead.
