Comment (by blair@…):

 So is the following correct, incorporating all the feedback?

 {{{
 variant universal {}

 build.cmd       ${prefix}/bin/scons
 build.args      CC=${configure.cc} \
                 CPPFLAGS=[join "${configure.cppflags}" ,] \
                 CFLAGS=[join "${configure.cflags},[get_canonical_archflags
 cc]" ,] \
                 LINKFLAGS=[join
 "${configure.ldflags},[get_canonical_archflags ld]" ,]
 }}}

 Ryan, feel free to commit any changes you want.
