This patch fixes compilation/linking of python third-party extensions, i.e. Extensions that ship with C code. Problem: Python uses distutils(-native) to compile third-party extensions. distutils uses its own sysconfig module to get the options for compiling and linking. Since third-party extensions have to be linked against this libpython it important that -L points into staging. This is not the case because distutils.sysconfig uses a special Makefile that is shipped with python determine the paths. The Makefile is the same that would be used on the target to build third-party extensions. It therefore points into /usr/lib instead of staging. Solution: Stage a modified version of the Makefile where the paths (incdir, libdir) have been replaced by ones that point into staging. Side-problem: The recipe actually should not stage files itself in do_compile, but rather handle everything that needs to be staged in do_install. This is currently not possible because python compiles itself using distutils-native. Distutils on the other hand does only allow to add a path, but not to substitute it, requiring a staged Makefile and libpython.so before the actual python compilation is triggered. The second step to solve this would be to either patch distutils, or split python into python-initial and python. The -initial part could create the Makefile and the library, while the main part focuses on the target.
