If you were asking how to do this within a Portfile, yes, that's how you would
do it. However, note that we don't want any Portfile to use -march flags, no
matter what architecture, unless within a variant called "native", since -march
flags enable features specific to some processor whereas we want to produce
binaries that could run on any processor.
