PSPP-BUG: [patch] Allow xgettext to be overrided in configure

[Petter Reinholdtsen]

Please consider the following patch for pspp.  It allow the program
xgettext used by configure to be replaced.  I ran into the need to do
this when needing to set some extra parameters for xgettext in our local
environment.
