Yes, I believe so as well. We have this every year when gcc receives an update.
For the past several years I've tried to fix this but I was unable to test the
results as the submission already caused such a rebuild. 
Of course, this will also happen once Marcus' submission has made it to
Factory.
The gnu-compiler-hpc packages need to be rebuilt fully every time when a new
version of the package arrives. Not sure how to trigger this.
We can leave the current behavior as is and use the bug report that eventually
someone will file as a reminder to update the flavor list or ask someone more
knowledgeable than me about an idea how to trigger this rebuild.

Maybe Dominique can help ...?
