build_arch and configure.build_arch are not equivalent. The former
reflects what is set in macports.conf and is not meant to be modified
(and it's only a variable, not an option, to reflect this.) The latter
is what will actually be used when generating the archflags passed to
configure, can be changed by the portfile, and has a default value based
on build_arch but possibly changed because of supported_archs.

configure.universal_archs and universal_archs are analogous to
configure.build_arch and build_arch, respectively, and are used instead
of them when the universal variant is set.
