The other targets (right now, I guess that would mean freebsd) don't even pretend to support debugging via lldb-server, so we should not fail their build because of that. Check for usages of CMAKE_SYSTEM_NAME to see how to discriminate those.

One of my big goals for the future of testing on LLDB is to get to the point where the only differences in test coverage when running tests on different hosts is truly platform-specific code. Today we are nowhere near that.

> There is some llgs (debugging) support in lldb-server, but I have no idea what's the state of it -- it was added by Todd during his week of code as an "NFC" commit, and it hasn't been touched since. I'd like to avoid this keeping the build red if there is no intention of working on it.

I don't know the state of this stuff on Darwin either. I had spent a little time a few weeks ago trying to get lldb to use lldb-server on Darwin to see if I could answer that question, but I didn't get very far before I had to stop.

As long as the Apple exclusion is temporary I'm fine with this as-is. I'll see if I can free up some time this summer to look more closely at lldb-server on Darwin and figure out what state it is in.
