codeblocks: needs C++11

[mojca (Mojca Miklavec)]

Codeblocks currently fails to build without C++11 compiler:

I'll test whether using the cxx11 1.1 PortGroup is sufficient.

I tried to use the cxx11 1.1 portgroup, the compilation runs smoothly, but it then crashes with

I couldn't get anywhere building it on 10.6 with libc++ and clang-3.9. I think it might be related to the precompiled headers?

I tried enabling this:

configure.args-append   --disable-pch

but that didn't change anything.
