bug#23870: Guile 2.0.11 can't find clock_getcpuclockid on macOS 10.12 Sierra

Guile version: 2.0.11
Machine type: x86_64-apple-darwin16.0.0
macOS 10.12 introduces the `clock_gettime` family of functions, with slight
differences from the *BSD and Linux implementations.
The failure in linking is caused by a call at libguile/stime.c @ L841 to
`clock_getcpuclockid`, which does NOT exist on macOS, while `_POSIX_CPUTIME`
and `CLOCK_PROCESS_CPUTIME_ID` do exist.
I have an absolutely hideous patch locally applied that gets things
compiling (and get-internal-run-time seems to work), but is otherwise terrible
from a readability and maintainability standpoint. That said, narrowing it down
to that single call should help make this fix easier.
