Nope, I explicitely asked him to build that code for all arches, as we want to process s390 perf.data files on a x86 or arm or any other arch.
I stumbled on this as well, I think the way to go is to get the color_fprintf bits in a separate object to avoid dragging more stuff to the perf binding set of objects and then add that to the python binding.
