Using 64bit time on 32bit targets was only introduced in Linux 5.1.0.
On versions prior to that, compiling uClibc-ng produces incorrect headers
that cause the `clock_nanosleep` syscall to receive incorrect arguments.

Without this change `timespec` is too large for the `clock_nanosleep` syscall,
which translates to sleep(0) on 32bit systems when TIME64 is enabled (the default).
Tested on MIPS.
