ARM support

[mishka]

Hi everyone!

Could you please compile it for ARM as well so we could run it on devices such as raspberry pi?

I tried to compile on centos7-aarch64. npm install and npm run pack finish successfully but the generated release/orca-1.2.1-arm64.AppImage does not work:

[me]~/orca-3.3.4% release/orca-1.2.1-arm64.AppImage --help
[me]~/orca-3.3.4% echo $?
1

npm run test:unit fails on every major test:

test/unit/server_test.js ............................ 14/34 17s
  createServer: > should reply pong to ping post
  not ok should be equal
    +++ found

Any ideas on this?

I use the recommended node and npm:

[zyang@kunpeng920]~/orca-3.3.4% which node
~/node-v8.17.0-linux-arm64/bin/node
[zyang@kunpeng920]~/orca-3.3.4% which npm
~/node-v8.17.0-linux-arm64/bin/npm
