Setup the gcc 6 by rpm package without compiling by myself.

Setup the gcc 6 by rpm package :
Firstly, I downloaded the gcc6 source code from official website compiling it by myself.
When I compiled the to-be-fuzz kernel, it show do not support -fsanitize-coverage=trace-pc by compiler.

And then, I saw above libraries installing them.
