port only builds with build_arch=i386 on command line -- any way to specify that in the portfile?

If you want to change the optimization flags, set e.g. "configure.optflags -O2". MacPorts will automatically add it to cflags, cxxflags, and other appropriate flags.

But only do this if this software requires it. Otherwise, let MacPorts use its default value of -Os.
