Fixing _sysconfigdata*.{py,pyc} was previously done by python package
infrastructure. Some packages use python stuff without using python
package infrastructure.
These packages perform overwrites and need the specific python fixup
to fix them.
In order to be sure to fix all of these packages, the python fixup
is moved to the generic package infrastructure and applied to all
packages.
This follows the same principle as for the .la libtool files fixup.

# Python package infrastructure
|
|
#
|
|
# This file implements an infrastructure that eases development of
|
|
# package .mk files for Python packages. It should be used for all
|
|
# packages that use Python setup.py/setuptools as their build system.
|
|
#
|
|
# See the Buildroot documentation for details on the usage of this
|
|
# infrastructure
|
|
#
|
|
# In terms of implementation, this Python infrastructure requires the
|
|
# .mk file to only specify metadata information about the package:
|
|
# name, version, download URL, etc.
|
|
#
|
|
# We still allow the package .mk file to override what the different
|
|
# steps are doing, if needed. For example, if <PKG>_BUILD_CMDS is
|
|
# already defined, it is used as the list of commands to perform to
|
|
# build the package, instead of the default Python behaviour. The
|
|
# package can also define some post operation hooks.
|
|
#
