# Some of CPython's source code is generated using Python interpreter
# and some helper tools such as "Programs/_freeze_importlib" or
# "Parser/pgen" (look for regen-* targets in Makefile.pre.in for more
# info). Normally CPython codebase ships with those files
# pre-generated, so just regular "make" with no additional steps
# should be sufficient for a succesfull build, however due to
# Buildroot's "Add importlib fix for PEP 3147 issue" custom patch we
# end up modifying "Lib/importlib/_bootstrap_external.py" which means
# we have to do "regen-importlib" step before building CPython
# (Importlib is a builtin module that needs to be "frozen"/converted
# to a C array of bytecode using "Programs/_freeze_importlib")
#
# To achive that we add pre-build steps to host-python3 as well as
# python3 that execute "regen-importlib" target.
#
# Unfortunately, for the target Python, "Programs/_freeze_importlib"
# is built for the target, while we need to run them at build time. So
# when installing host-python3, we copy them to $(HOST_DIR)/bin...
