There is a define in the Makefile that defines OFF_T to off64_t for
_FILE_OFFSET_BITS=64 but that looks like a workaround for buggy libc.

The _FILE_OFFSET_BITS=64 should, when code is compiled on 32bit
platform, change the 32bit off_t to a 64bit off_t.

I.e. when you compile following:

int main(void)
{
        printf("%zu\n", sizeof(off_t));
        return 0;
}

on a 32bit (or with -m32) it should print 4
on a 32bit with -D_FILE_OFFSET_BITS=64 it should print 8
on a 64bit it should print 8 regardless

As far as I can tell we should remove the OFF_T handling from the
Makefile here instead.
