This should be wrapped in an ".if exists(${PYTHONBIN}", otherwise
users and bulk builds will get strange errors when running non-build
targets in that directory.

Also might be worth changing the variable to PYTHON_PLATFORM or
something, PLATFORM seems generic enough that it might be used at some
point in the infrastructure.

Otherwise I'm fine for this to go in during the freeze.
