il2cpp build for Playstation 4 taking long time

Hello, I am trying to make a master submission build for PS4.
And it used to work fine before but now it takes forever to build.
I am on Unity 5.3.4p5 version.
I am trying to make a full package build since last night,
it’s been 17hours but still hanging on scene 19.
Before making this package build, I deleted library folder since
some people mentioned that deleting library would help.
Why is this happening? and how to resolve this issue?

Can you determine what process is taking a long time? Is there a specific il2cpp.exe process or a compiler process that seems to hang? If so, can you provide the command line arguments for that process? That might help us track down the cause of the issue.
