this question is quite old, but I have the same issue at the moment and didn't find another way to silence it.

IMHO an ideal solution would be a compiler option where you can provide the the minimal compiler version that your code is compiled with. This should silence (irrelevant) ABI infos involving older compilers but still shows relevant infos.

I would like to suggest this to the gcc developers but I don't see a way to do that: I cannot create a bugzilla account, because it is not possible automatically and an email request bounces.
