Hi Tim,

It is useful addition. Output is hard to read though. It would
be helpful to improve the printing targets.

make -C tools/testing/selftests/ show_targets
make: Entering directory '/lkml/linux_5.7/tools/testing/selftests'
android arm64 bpf breakpoints capabilities cgroup clone3 cpufreq 
cpu-hotplug drivers/dma-buf efivarfs exec filesystems

pidfd pid_namespace powerpc proc pstore ptrace openat2 rseq rtc seccomp 
sigaltstack size sparc64 splice static_keys sync sysctl timens timers
