[PATCH] [OPENMP] Added option -fopenmp=libiomp5|libgomp

[Dmitri Gribenko]

  > -fopenmp is used only to link libgomp library, -fopenmp= is used to activate processing of OpenMP constructs and future codegen.

  This feels surprising, but I see where you are coming from -- codegen will only support libiomp5 interface.  Please document this behavior in the user manual.
