Move all tests out of the csu subdirectory
Stack-protection on .o files in csu/ must be suppressed for the sake of library startup code. This also suppresses stack-protection in tests (which are also covered by CFLAGS-.o), though this is neither necessary nor desirable. So impose the rule that .o files in csu/ are necessarily C startup code, and move the few tests in there into misc/ instead.
