Justin Hammond f4d71b6074 testing/libc/arch_libc: Time against a clock that runs.
Every measurement repeats until a stated interval has passed, so a clock
that reads the same value twice does not slow the benchmark down, it stops
it returning at all.

CLOCK_MONOTONIC does not advance on every target.  On qemu-intel64 it
reports success and stays at zero, while CLOCK_REALTIME advances normally,
and the benchmark spins in its first measurement with no output after the
heading.

Sample each candidate twice around a busy wait and take the first one whose
reading changes.  Where none does, say so and skip the timing rather than
hang.
