A possible workaround is to add --ccache-skip before each troublesome
parameter. Or rather: It should have been possible, but it's buggy in
3.0.1. It will be fixed in 3.1.

I didn't know about this specific clash, but there are others very
similar described in this bug report:

https://bugzilla.samba.org/show_bug.cgi?id=7556

You can create a new bug report if you want, or just leave a comment in
7556.

As noted in a comment to the bug report, I think that a good way to
handle this is to make ccache perform compiler detection (and cache the
results of it) so that it knows to (in this case) leave -xarch and
friends alone. I guess it's also feasible to introduce a ccache setting
that let's you select which kind of compiler you have, but it would be
nicer to handle it transparently.
