Daniel,
Perhaps the better way to go about it than to call scons N times is to have
N variant dirs? where there's a variant dir for each build type you want,
and then youd call
scons build_wheel
which is aliased Alias('build_wheel','variant_dir for building wheel path')
Maybe bring this up on scons users mailing list and we'll see if it can be
resolved?
