Subject: do not update po and pot files in the process of the build as this
 causes timestamp changes for the mo files which therefore can't be refcounted
 by dpkg for your M-A: same packages (Closes: #659333, LP: #924628)

The commit also enables a top-level 'make update-po' and does
all the needed changes to let this work now that update-po might
be called in a freshly checkout tree
