   4 # Python interpreter, to run its own python-config.py program, which
   5 # uses sysconfig. However, when cross-compiling, this doesn't work
   6 # well since we would have to use the host Python, whose sysconfig
   7 # module would return host values.

   9 # As recommended at
  10 # https://sourceware.org/gdb/wiki/CrossCompilingWithPythonSupport,
  11 # this wrapper shell script can be used as a replacement. It ignores
  12 # the python-config.py script passed as first arguments, and
  13 # "emulates" its behavior.
