Just tried boot-flag.patch with https://github.com/python/cpython/commit/16e07881bd3867d471dd0a25c5117672b65c90ee. Doesn't work out-of-box:

#./Programs/_freeze_importlib \
    ./Lib/importlib/_bootstrap.py Python/importlib.h
/bin/sh: line 1: ./Lib/importlib/_bootstrap.py: Permission denied
make: *** [Makefile:749: Python/importlib.h] Error 126

My fix is: merge the two lines into a single one. See my attached patch.

By the way, the BOOT hack is quite similar to GENERATED_COMMENT in introduced in issue27641. Maybe they can merge?

My environment:

* Arch Linux x86_64
* /bin/sh symlinks to bash, which is 4.4.12
* GNU Make 4.2.1
