Indeed, this is a topic discussed previously and we need to make the
distinction between host triple and target triple.

Furthermore, the -ccc-host-triple does not have the same effect than
"-cc1 -triple", which is yet-another way of setting host/target
options.

I don't mind setting the target triple manually and at the same time
specify cpu/fpu/etc as long as the behaviour is clear and we only have
one way of setting each.

In the past, when the same subject was discussed, the reason why we
have so many options was that Clang started as a wrapper for cc1 and
then became a full-fledged front-end with its own options but still
had (did it?) to support the old options. As with many other things in
LLVM, why not deprecate the redundant (and confusing) options? Is
there any strong reason to keep them (other than 'it'll break
builds')?
