For each device declared with DEVICE_= NATIVE_ENDIAN, find the set of

If the set of targets are all little or all big endian, re-declare
the device endianness as DEVICE_LITTLE_ENDIAN or DEVICE_BIG_ENDIAN
respectively.

This *naive* deduction may result in genuinely native endian devices
being incorrectly declared as little or big endian, but should not
