Looking deeper into this, it looks like the right solution is to use
sysconf(_SC_PAGESIZE) instead of getpagesize(). getpagesize() looks
deprecated, that's why it's getting disabled when modern features are
enabled. I'll send a patch to use sysconf when supported and fallback to
the old getpagesize() otherwise.
