Trying to compile to Linux ARM not working

I have tried using all the engines from 4.8 to 4.15 and no luck. Some of them build out but they will only build to x86 x64 not ARM and the engine that I got this far with don’t have a “UEBuildLinux.cs” file at all so I have no idea how to tell it to switch to ARM. On versions like 4.14 and 4.15 there is a “UEBuildLinux.cs” and I change it to ARM but when I go to package the project it just redirects me to the “How to compile for linux” page rather than actually compiling. I’m using toolchain clang-3.5.0-arm.
