Not able to build UE4

Hello Team,
I have downloaded the souce code of Unreal Engine from the below link :
A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums , and executed below steps:

1)git clone https://github.com/EpicGames/UnrealEngine.git
2) cd UnrealEngine
3) ./Setup.sh
4) ./GenerateProjectFiles.sh
5) make

On 5th Step , I am getting Clang errors while executing the “make” step.(Tried with Clang versions 3.8, 5 and 7)
Please find the snapshot of error which I am getting :

/UnrealEngine/Engine/Binaries/Linux/libUE4Editor-Persona.so: file not recognized:
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
clang++: error: linker command failed with exit code 1 (use -v to see invocation) Makefile:588: recipe for target ‘UE4Editor’ failed make: *** [UE4Editor] Error 5

Please assist in installing Unreal Engine and let me know where I am going wrong.
