Like this, tested only the make-flight bit and ran perl -c on
ts-xen-build to check syntax.

Subject: [PATCH] Apply PYTHON_PREFIX_ARG workaround to Xen 4.2 and earlier

...rather than applying only if the host is Squeeze, since this also happens on
Wheezy. Xen 4.3 onwards are not affected because they install to /usr/local
instead of /usr which avoids this particular issue.

The workaround is described in
http://wiki.xen.org/wiki/Compiling_Xen_From_Source#Python_Prefix_and_Module_Layout

We set PYTHON_PREFIX_ARG='' since that is what we did on Squeeze although that
is a specific quirk of Ubuntu and we could use --install-layout=deb.
