This isn't really necessary, is it?  It's still OK to explicitly specify the calling convention, right?  Are you just trying to get better test coverage for using the default ABI?

What's the default ABI for "-mtriple=armv6-elf" or "-march=arm"?  It isn't obvious to me whether those should use APCS or AAPCS, so maybe it is better to explicitly specify the CC in those cases.
