Test failed to build:
        stdout:
        cc -O -Wall -Wpedantic -Werror -c -o checktsc.o checktsc.c
        stderr:
        checktsc.c: In function ‘slave_thread’:
        checktsc.c:159:2: error: impossible constraint in ‘asm’
        __asm__ __volatile__("rdtsc" : "=A" (tsc));
        ^~~~~~~
        make: *** [: checktsc.o] Error 1

It looks like this has something to do with its assembly, maybe this test should be disabled on ARM64 like the monotonic test.
