Isn't that funny that, when we want to come up with a reasonable and
logical "triple", it actually has 5 fields? :)

That's why Clang and LLVM are desperately trying to move away from
triples, into separate flags. But if you separate the default from the
triple handling, we can re-use the default for the separate arguments
in the same way we use for legacy triples.

It does when we control the environment. On legacy systems, not even
the user does. :(
