Bug#1119124: boulder-game FTCBFS: multiple reasons

[Helmut Grohne]

boulder-game fails to cross build from source for two distinct reasons.

The immediate failure arises from hard coding the build architecture 
pkg-config in the upstream Makefile. The result is that a package cannot 
be found and the missing flags result in an #include not being found. 
Once making pkg-config substitutable, dh_auto_build is able to supply a 
host architecture one.

The other failure arises from storing g++ in CC. The CC variable is 
typically used for the C compiler, so dh_auto_build overrides it with a 
C cross compiler. That doesn't go well when the actual source is C++. 
Renaming the variable to CXX - the common variable for a C++ compiler - 
fixes this aspect.

I'm attaching a patch for your convenience. Please also consider 
forwarding it upstream.
