From 3fabaeec684fae934055b85c2f91c1bd700c71b0 Mon Sep 17 00:00:00 2001

Subject: [PATCH] setup.py: drop the pybind11 build dependency
pybind11 is only used for pybind11.setup_helpers.ParallelCompile, a
build-time helper that parallelises the C extension compilation. Pillow
ships no pybind11 bindings, so remove the import, the ParallelCompile
call and the pybind11 build-system requirement; the C extensions are
then compiled serially.
