[zhouxinyong]

Version
3.0.0-rc.3

Steps to reproduce
npm i -g @vue/cli
vue ui
create a project
run build in diffrent machine (one is ubuntu, the other is window)
What is expected?
the file hash is same after build in diffrent machine

What is actually happening?
the chunk-vendors hash is same in diffrent machine
but the app.js and app.css hash are not same!?

Is there any solution to fix this problem?
I Have update vue-loader to 15.2.6, but the hash still change in diffrent machine.
