Not sure I understood Paolo's suggestion, I tried:

-- >8 --
diff --git a/Makefile b/Makefile
index bcbbec71a1c..3ef3622228b 100644

 # Force configure to re-run if the API symbols are updated

But still get (after git pull this morning):

$ ninja qemu-system-ppc
[0/1] Regenerating build files.

I'm keeping the directory unmodified in case you want me to try
other fixes.
