For big-endian machines, we have to make sure that the
length is stored in little-endian format, since this is the
format used for the binlog.
We do this by setting the db_low_byte_first, which is used
inside some store_length() to decide what order to write the
bytes in.
In reality, db_log_byte_first is only set for legacy table
type Isam, but in the event of a bug, we need to guarantee
the endianess when writing to the binlog.
This is currently broken for NDB due to BUG#29549, so we
will fix it when NDB has fixed their way of handling BLOBs.
