This completes the transition started in Knight scripts during their M2libc
migration at f2094a9e5b
from : to
--BaseAddress : --base-address
--BigEndian : --big-endian
--LittleEndian : --little-endian
The plan for mescc-tools is to deprecate the old (pre-1.0.0) flags.
Note that test0101 compiles "hex2 0.3" and verifies that it works by
linking an example. This 0.3 version requires the old-style flags, so the
calls to test/results/test0101-*-binary are left unchanged.
