Fails to build with multiple CXXFLAGS

[GoogleCodeExporter]

Hi,

(I am currently updating the Pingus Debian package)

Building pingus with more than one CXXFLAGS passed to scons on the command line 
fails. For instance:
scons CXXFLAGS='-g -O2'

A bit of investigation shows that this is because CXXFLAGS are passed as list 
in SConscript and scons doesn't mix well strings and list. I asked on the scons 
mailing list and the best answer I got was to use SCons.Util.CLVar.

The attached patch fixes this issue accordingly, please include it in the next 
version of Pingus.

Thanks,
Bertrand
