Description
Building with "-march=native" in CXXFLAGS results in the error below. This is the correct setting for the CPU I have installed (AMD FX(tm)-8320 Eight-Core Processor).
I don't think it makes sense to raise an error based on a particular combination of CPU instruction set extensions. I think this error should be removed.
