Oh. This has broken my U-Boot build/test system. I guess it's entirely 
my fault for interpreting the "2018.01" warning as "you'll need to fix 
this in Jan 2018", not "you'll need to fix this as soon as development 
starts for 2018.01":-(

Is there a reason for requiring such an extremely new gcc, as opposed to 
simply something not ancient? For example, no LTS version of Ubuntu 
packages a compiler that's new enough to build U-Boot now:-(
