Polyorb first version available

[Xavier Grave <xavier.grave@ipno.in2p3.fr>]

Hi,

At least, rev 79d029250b63dd2118188370321ab18cd61eb041 of 
org.debian.polyorb
produces usable (from a DSA point of view) code.
There is still the lintian error :
 E: polyorb source: license-problem-gfdl-invariants 
docs/polyorb_ug.texi
which is related to this bug #709495

Taking inspiration from org.debian.gprbuild I should close both bug and 
lintian warning.

My questions :
How do I close #701338 ? One line explaining that polyorb build depends 
on gcc-4.9 is enough ?
Do we upload to experimental 2.11~20140128-1 in order people can play 
with it as soon as possible ?
