For each device declared with DEVICE_NATIVE_ENDIAN, find the set of
targets from the set of target/hw/*/device.o.
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
introduce regressions for current targets.
These devices should be re-declared as DEVICE_NATIVE_ENDIAN if 1) it
has a new target with an opposite endian or 2) someone informed knows
better =)
