[bug#31431] [PATCH 0/1] gnu: Add pybind11.

[Fis Trivial]

pybind11 is a c++ library for python binding. I don't know if it's
appropriate to put it in python.scm. I checked libffi, libffcall, swig,
they all have their independent file, and all of them contains very few
packages.

Should I merge them into one file just named "ffi.scm"?
