Some tools seem to generate multi-parts rar where only the first chunk
contains the actual file size.

If the event is ignored, the Qt4-X11 will reject the quit ICCM request.
This annoyingly caused VLC to inhibit logging out.

As we need to build contrib before running configure, this remains a
little bit awkward:
 # cd builddir
 # mkdir contrib
 # cd contrib
 # ../../contrib/bootstrap
 # make

Also get rid of "hosts/" in the install prefix. Because I can.

'make clean' removes those, so there is no point in creating them from
