Fix some sanity checks

Update: Changes that made it not to work dropped.

* Fix `building_llvm` in sanity check
  * This was subtly broken: we build LLVM if any of the hosts builds LLVM, and not setting the config meant that LLVM is built for that target. Because of filtering away the targets not configured and the semantics of `Iterator::any`, it currently didn't set the `building_llvm` flag even if we indeed build it.
* Add `swig` sanity check
  * This checks whether there is a `swig` executable needed for LLDB.
