[GIT PULL] gcc-plugins update for v4.8-rc1

[Kees Cook]

Hi,

Please pull this new gcc-plugin for v4.8-rc1.

This is the next gcc plugin from Emese Revfy, funded by CII, and builds
on the new gcc-plugin infrastructure now present in Kbuild. It provides
a way to generate additional entropy at boot and runtime, which is
especially helpful for embedded systems.

Thanks!

-Kees
