In addition to doing the bump, this commit also: - Refreshes all the patches - Removes python-003-properly-detect-if-python-build.patch, which has been applied upstream. - Passes the --without-ensurepip option, like is done in Python 3, to avoid having Python use PIP to automatically download stuff when it is being built. - PYTHON_LIBTOOL_PATH = NO is added to prevent Buildroot from trying to patch a version of libtool for which we don't have matching patches, which isn't a problem since we're anyway not using the part of the Python sources that uses libtool (it's the built-in copy of libffi, and we use the external libffi).

python: do not rely only on LIBRARY_PATH for old compilers
|
|
|
|
The cross-compilation improvements integrated in Python rely on the
|
|
compiler exposing a line starting with LIBRARY_PATH when called with
|
|
-E -v. This is used by Python setup.py to find the installation
|
|
locations of libraries.
|
|
|
|
However, this LIBRARY_PATH line is not shown by very old compilers,
|
|
such as the gcc 4.2.x compiler used on the AVR32 architecture. This
|
|
causes libraries installed in the sysroot, such as libffi, to not be
|
|
detected by the setup.py script.
|
|
|
|
To fix this problem, this patch adds addtional logic to setup.py,
|
|
which consists in deriving the library paths from the sysroot
|
|
location, if no LIBRARY_PATH field was found.
