I think that you should fix the tests.  Your gas port is behaving
correctly, it is the tests which are incorrect in their assumption of
the size of a byte.  I would try, if possible, to add alternative
versions of the expected output scripts that match 16bit bytes, and
then have the test driver scripts (*.exp) select the correct expected
output based on the architecture's byte size.
