Ed Maste e9093b66d5 Add kernel retpoline option for amd64 
Retpoline is a compiler-based mitigation for CVE-2017-5715, also known
as Spectre V2, that protects against speculative execution branch target
injection attacks.

In this commit it is disabled by default, but will be changed in a
followup commit.
