Windows: support static build and enable ASLR and NX

[rdoeffinger]

Without these linking against a static Qt still needs libgcc_s_sjlj-1.dll and libstdc++-6.dll, which I think is not desirable.
Enabling ASLR and NX should be a good idea always.
Haven't really tested except compilation and starting with WINE though.
