According to https://build.golang.org/#short, it looks like CL 49530 is the first bad commit. /cc @williamweixiao @cherrymui

It seems to be affecting only macOS 10.12, but not 10.11, 10.10, 10.8. Also linux-arm64-buildlet and linux-arm64-packet, but not other types of Linux.

arm64/arm64asm: avoid log.Fatal during test
ffd22fb 
Especially log.Fatal(err) where err came back from exec.Command.Run.
It prints no additional information and is very confusing for the test
to die printing 'exit status 1'.

For golang/go#21486.

Reopen. ARM64 failure is still not fixed. A revised CL https://golang.org/cl/56810 should handle it.
