feat: support additional GOOS/GOARCH targets

[maier]

Add support for additional targets:

GOOS=illumos GOARCH=amd64
GOOS=aix GOARCH=ppc64
GOOS=android GOARCH=386
GOOS=android GOARCH=amd64
GOOS=android GOARCH=arm64
GOOS=plan9 GOARCH=arm

@caarlos0 I just noticed issue 1160, I can add the remaining new GOOS/GOARCH combos from go1.13 to this PR if you'd like. (sans jswasm which you have in another PR.)

[caarlos0]

that would be awesome. I did jswasm in another pr because it needed more things (.wasm ext), if that's not the case with the others, feel free to do it.

FWIW will merge that PR as well.

Thanks 🚀
