[MT patch]: lowercase architecture names

- Subject: [MT patch]: lowercase architecture names
This patch changes the mt assembler to only accept lowercase architecture names,
in line with existing practice. GCC's multilib support forced lower case names
and now gcc itself is case sensitive. The patch also changes the default to
ms1-16-002, which is the same as gcc's default.
ok?
