Nothing built-in, no.


boost uses:

if {[lsearch ${build_arch} *64] != -1} {

and

if {[lsearch ${universal_archs} *64] != -1} {


python24 has:

if {(![variant_isset universal] && ![string match *64* $build_arch]) || ([variant_isset universal] && ![string match *64* $universal_archs])} {


Seems to me like you could simplify that using [get_canonical_archs].
