scons: Fix glew build on MSVC.
The environment for building the DLL needs to be quite different from
the environment for building the programs, in order to get
the dllexport/dllimport attribute done currectly. I don't know how MinGW
managed to build the programs, but MS linker refuses to link symbols with
mismatching attributes.
