features.h: error out when attempting to compile with TIME64 for 32bit targets on Linux versions prior to 5.1.0
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.
