Sorry, not yet. This week was rather busy, but my intention is to give it a try
today or tomorrow on that machine. First I need to do some sport :) Then this will
be top priority

Up to now I have only interpreted the presented log:

/<<PKGBUILDDIR>>/obj-x86_64-linux-gnu/tmp_gen/builtin_pybind11.cpp is create by 
the generator program. Somehow CMake notices that and remove the first file A.cpp
that is generated by the generator program. As the next step needs that file the
generation is tried again and must fail. This failue is not detected until the compilation
error occurs.

I have no idea why writing of the file fails. I will probably have to patch the
generator program to do some error checking (that is currently missing). I think I saw
this same error for buildd on some not officially supported architectures, but never on amd64.

Best,

Markus
