When consistent, it should use common infrastructure - and so no longer -m
options - see my posting giving proposed documentation for --arch and
--tune options, much as suggested by the discussion two years ago. If
Neil's target structure patch goes in first, the tables of architecture
variants and their --help descriptions can then go in the target
structure, rather than needing to define more target macros.
