Subject: R explicitly built without support for OpenMP
OpenMP takes a LONG TIME to build, so to keep things reproducible we are
explicitly disabling OpenMP, if a user needs OpenMP, its trivial to just
add it as a prerequisite of R. The problem is that in some scenarios (based
on other dependencies and when they were built in the build directory),
OpenMP may be present when R is being installed and in other it may not. We
don't want the result to be different between the two builds.
