Thanks for mentioning this. I've reverted the change for now and
will have a look tomorrow.
The logs of the failing bots are not very informative about what
is going on:
gcc -pthread -c -Wno-unused-result -g -O0 -Wall -Wstrict-prototypes -I. -I./Include
-DPy_BUILD_CORE -o Python/dynamic_annotations.o Python/dynamic_annotations.c
gcc -pthread -c -Wno-unused-result -g -O0 -Wall -Wstrict-prototypes -I. -I./Include

./python ./Python/freeze_importlib.py \
 ./Lib/importlib/_bootstrap.py Python/importlib.h
make: ./python: Command not found
make: *** [Python/importlib.h] Error 127
program finished with exit code 2
vs.

I guess some commands are not printed to stdout.
Looking at the buildbots again: reverting the patch has not caused
the lights to go green again. Very strange indeed.
Looking further I found this line in the Makefile:
############################################################################
# Importlib
Python/importlib.h: $(srcdir)/Lib/importlib/_bootstrap.py $(srcdir)/Python/freeze_importlib.py
 ./$(BUILDPYTHON) $(srcdir)/Python/freeze_importlib.py \
 $(srcdir)/Lib/importlib/_bootstrap.py Python/importlib.h
Since the patch modified _bootstrap.py, make wants to recreate importlib.h,
but at that time $(BUILDPYTHON) doesn't yet exist.
