Ah, I didn't realize that. I also just noticed that the two arch_timer
functions we call here are inline functions that just access control
registers.

If we want to enable COMPILE_TEST then, it would have to be something
like 

#ifdef CONFIG_ARM || CONFIG_ARM64
#include <asm/arch_timer.h>
#else
... /* stub functions */
#endif

That might still be helpful to get coverage from things like the public
coverity builds that always build x86 allmodconfig, but it's also a bit
ugly.
