Rather than split this into a separate test, I think it would be more normal to have these test cases in `sparc-elf-headers.test` too. You can use yaml2obj's --docnum option, if you can't sensibly share the YAML docs, although in this case, you could just parameterise the machine type via -D, like you do with the flag.
