Nw addon link issue with STL structure.

[Jian Wang]

I'm working with nw-gyp but failed to link any lib using STL structure. I've made an isuue here https://github.com/nwjs/nw-gyp/issues/150 . I guess the reason my be gyp tool is too old, and also I struggled to compile with SSE or AVX support. 

I've tried  and "-march=native", "-mavx2", "-msse4.2" cflags in .gyp , but none of them work for me. (These are all I could found for node gyp on Google). Really need help for me.
