My workstation at work is amd64 and I have a 20 node amd64
cluster. All of these systems run freebsd-current. I've
only had a few problems when building ports.

Without it, the build infrastructure was selecting -march=i486,
which produced even worse results. Several ports would not
compile because llvm's integrated assembler was given invalid

FFLAGS are the options used while compiling Fortran. Having
spent years contributing to and testing gfortran, I am fairly
comfortable with these options.
