Most of the instances where I want to use this, I want to do it outside of a phase, as in:

variant universal {}
if {[variant_isset universal]} {
    set archflags ${configure.universal_cflags}
} else {
    set archflags ${configure.cc_archflags}
}
build.env CC="${configure.cc} ${archflags}"

But it should be fine to do this right?

variant universal {}
build.env CC="${configure.cc} [get_canonical_archflags]"
