    $ man 3type stat
    [...] glibc exposes the nanosecond component names if
    _POSIX_C_SOURCE is defined with the value 200809L or
    greater, or _XOPEN_SOURCE is defined with the value 700
    or greater.

In uClibc-ng, they are guarded by __USE_MISC, which is defined by
_BSD_SOURCE || _SVID_SOURCE, which are each stated to be equivalent
to defining _POSIX_C_SOURCE to 200809L or greater.

Applied to master, thanks.

Regards,
Yann E. MORIN.
