Wouldn't it be possible to use the dpkg-buildflags framework for this? As 
far as I understand it, this framework sets the gcc options used to build 
Debian packages. Using it would allow to have an upstream-like gcc for the 
whole system, and Debian-specific options when building packages.

(It would also have the side-effect of making sure all packages actually 
work fine when dpkg-buildflags sets something different as usually 

Opinions ?
