That's what -xMF is there for, just like -MF for gcc.
I can't see how it would work though, at least for me
only the basename is printed before the :, not the path.

Maybe that's because the stuff is in opt. I don't get that with default

between -xMD and -xMMD is that the later should not have these
-> it's a bug, we shouldn't care about it.
