Won't compile on classic App Engine

[derekperkins]

I'm not using this directly, but via compress/gzip, and I get this error when compiling for use on App Engine. It currently is using Go 1.4.2 and I believe it can't compile assembly. Would it be possible to add a build flag to support it?

Compile failed:
2015/12/14 16:39:45 go-app-builder: build timing: 77×6g (10.91s total), 1×6l (1.511s total)

Thanks for the report!

Is it possible for you to test PR #8

If you'd rather have it in master, I don't see a huge risk in merging it.
