        The choice OPTION=yes checks for the availability of the facilities

+       in libc.  OPTION=rt also checks in
        librt (and, if it's needed, links to it).  Note that linking to librt
        is not always desirable because for glibc it requires linking to
        libpthread too, which causes all reference counting to use atomic
