 Can you try `make mrproper' (stash away your .config) and see if the 
problem goes away?

Indeed, 'make mrproper' did the trick. I am sorry for the noise. Until
now I never had to use mrproper before and therefore didn't think of it.

 People have been being hit by stale generated files recently and I reckon 
effort has been taken to address the issue by removing them automagically 
somehow on rebuilds.  Until that has been complete you're advised to clean 
your build tree after an update, or maybe rebuild speculatively and then 
clean only if something actually breaks.

FWIW, I just found out that running mrproper before building
fuloong2e_defconfig is fixing the problem reported kbuild robot too.
