diff: another fix for my linkage mismatch change

[Fergus Henderson]

Another fix to make things work with my change to
ensure that the declarations and definitions for data constants
specify the same linkage (extern or static).

tests/valid/headvar_not_found.m:
tests/valid/subtype_switch.m:
	Add definitions for types which were declared but not defined.
