objtool orc+mcount ?

That is, have '+' be a separator for cmd thingies. That would of course
require all other arguments to be shared between all commands, which is
currently already so, but I've not checked the mcount patches.

Alternatively, we ditch the command thing entirely and live off of pure
flags:

'o', "orc", "Generate ORC data"
'c', "mcount', "Generate mcount() location data"
