Subject: [PATCH] Makefile: Set CGO_ENABLED=0 for runtimetest

And also set '-installsuffix cgo'.  runtimetest is designed to be run
from inside a container, which may include a mount namespace that has
no linker or dynamic libraries.  These changes give us a static
runtimetest binary [1,2] which will work in those conditions.

     Subject: cmd/go: With Go 1.4, cannot statically link a program
       which imports net
