CPU_TIME_IS_THREAD_LOCAL

If it defaults to NO in the unknown case and the accounting actually is thread local then there's a big risk that gethrvtime starts returning negative values.

The UNKNOWN case should never happen if the configure test works, but I wasn't sure enough of that. I made a fallback instead of an AC_MSG_ERROR since I thought it would be annoying if the builds fail utterly because of it.

Is the UNKNOWN case meaningful? Shouldn't there be process global accounting in this case too? The global variable isn't even declared unless CPU_TIME_IS_THREAD_LOCAL has the value `NO'.
