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

...as long as -O2 worked. Experience from FreeBSD and from early MacPorts
experiments with -O2 is that it took -O2 a long time to actually generate
correct code in a majority of cases.
That said, it might be worth looking at again --- but, -O2 reportedly still
causes occasional problems for some programs, so be ready to bail back to
-Os.
