[git commit] sysconf.c: the clock_getres function is good for NPTL as well

[Bernhard Reutner-Fischer]

commit: http://git.uclibc.org/uClibc/commit/?id=df87a0f21e673bd4d79b174a39d8a72d5cac37ef
branch: http://git.uclibc.org/uClibc/commit/?id=refs/heads/master

Even if glibc reuses the syscall (bloat), we can reuse the function.
Make sure, that we use it only if it is provided by the syscall
and the function is really around (UCLIBC_HAS_REALTIME disables it),
else we get into a loop.
