Most of that is because the lisp data is dumped independently now. I
think about 50Mb is because of the lack of debug symbols. The duplicated
executables are no longer an issue, though, since the data is only
stored once.

libxml2 is a dependency, so it should be there in the versions with
dependencies. If it isn't working, then it's a bug.

No, the pdmp file is where all the dumped lisp data went. My release
builds (but not the snapshots) are all clean, so leftovers shouldn't be
possible.
