GCC 5 now the default in wily (release pocket)

As of today, none of our CI jobs are building any longer.
It looks like gcc 5 is now the default in Jenkins, but the libraries that are installed are still compiled with 4.9.
So, for example, we fail to link against leveldb because leveldb still has the old ABI string symbols in it.
The boost -dev packages also appear to still be at 1.55 with the old ABI. I expect that more things will
will be affected. For example, Qt5, with methods such as QString::fromStdString().
Is anyone looking at this?
