Avoid the need for Configure time 128-bit int detection

We just detect this at compile time instead.

This avoids cross-compilation problems where the host platform supports
128-bit ints, but the target platform does not (or vice versa). This was
causing a problem on some platforms where, dependent on the CFLAGS, 128 bit
ints were either supported or not.

Fixes #14804
