Fixing the mingw cross gcc. I set it not to build shared libraries, because its specs for 

shared libraries are wrong.
It should run "-lstdc++ -lsupc++" if libstdc++-6.dll is available, and instead it runs
"-lstdc++" and therefore lack symbols.

I think simply few people use shared gcc libs on mingw.
