We enabled time64 by default in uClibc-ng a while ago. With 1.0.51 you will get: #error 64bit time on 32bit targets is not supported on Linux < 5.1.0
We somehow need to handle UCLIBC_USE_TIME64 inside Buildroot and disable it for Linux < 5.1.0 systems.
Any idea how to manage it?
Like this (totally untested):
