Afaics, this is a warning by default. So the mere existence of
-std=c++11 does not make said package ftbfs, only if you combine that
with -Werror.
It would also be good to have an actual list of packages which FTBFS
because of that.
I recompiled all rdeps of libsigc++2.0-dev/libglibmm2.4-dev before
applying that change and did not notice any build failures because of that.

The alternative to dropping the .pc file hack is to have ~90 RC bugs
[1]. As said, it would be good to have an actual list of packages
failing to build because of that change. This would make it easier to
evaluate the situation.
If there are only one or two, dropping -Werror for those package seems
like the better alternative then having to touch 90 packages.

CCing Emilio in his role as release manager. I talked to him about this
issue before making this change.

Let's hear his input.
