I don't know why these are different.
That's because db(3) files have an endianness, which defaults to the
appropriate endian of the target platform. db(3) does support
automatically reading files of the "other" endianness though.

Yes, see above.

These could probably be always installed, but I haven't looked at the

Yup, /usr/share should be (NFS) sharable amongst various MACHINEs.
