[Python-modules-team] Bug#950138: pikepdf: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
pikepdf could not be built reproducibly.

This was due to two reasons:

a) The documentation included tutorial/walthrough like output like so:

   <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=1000x1520 at 0x7F04BAC72B90>

   … where the 0x7F04BAC72B90 part is non-determinstic and thus varies
   between builds.


b) The .cpp input files were compiled/linked in an order that was
   determined by their layout on the filesystem which is, at least in
   UNIX systems, non-deterministic.

Patch attached that addresses both these issues.
