    python-cython: mangle scripts to use /usr/bin/env python
    
    This prevents runtime failure "bad interpreter: No such file or directory"
    from running native cython when the native python is installed
    at a long path, exceeding the 128-character limit for shebang lines
    on linux. Exceeding the limit was already possible when using a long
    path for topdir, but it got easier to exceed after the switch to per-recipe
    sysroots.
