Right. We went through a few iterations of this with the Hexagon guys, who are actually using prefixes. In your case, the best thing to do is leave 'target' empty if you want unprefixed executables; this means "target matches host" and AFAIK matches GCC's behavior. (At least, it's what our autoconf does. Before 3.2, we had program prefixes completely disabled, so you couldn't even set one manually. Now you can set one manually, but you also get the default behavior of prefixing for "configurations that look like cross-compilers".)

Since Clang doesn't actually need different binaries for different targets, there shouldn't be any reason to set 'target' anyway.

Since we aren't really using "target" the way GCC does, I'm not sure what the "expected" behavior is, but the documentation is a good point. cfe-dev, should this be recorded somewhere?
