[GSoC] Check architectures

[Andreas Tille <andreas@an3as.eu>]

Hi Emmanouil,

I usually have some fun with trying unusal options and thus tested

   blend-gen-control --architecture xyz ...

which is properly handled by

   get_available_architectures(self)

I was happy to see this test because it is flexible enough to cope with
any new arch or those we are possibly droping in the future.  The only
change I would like to suggest is

$ git diff
diff --git a/blend-gen-control b/blend-gen-control
index 1a81aa1..7e28ff0 100755
--- a/blend-gen-control
+++ b/blend-gen-control
@@ -86,7 +86,7 @@ class UDD_connector:
         """
         It queries the UDD and returns a list with all the available Debian architectures
         """
-        query = "select distinct architecture from packages"
+        query = "select distinct architecture from packages where architecture != 'all'"
 
         self.__execute_query(query)
 

Kind regards and nice to see your code evolve

      Andreas.
