The choice OPTION=yes checks for the availability of the facilities
- in libc and libposix4. In case it's needed the latter is also linked

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
