Wouldn't it perhaps be nicer just to unexport these?

I think

TARGET_CPPFLAGS[unexport] = "1"

might do it or we could do:

delvarFlag("TARGET_CPPFLAGS", "export")

?

Regardless of approach, this is likely going to need some extensive
testing.

Unexporting is certainly neater, but a world build with poisoned flags
would certainly catch anything that's doing it wrong (openjdk for example
appears to be passing build cflags to host g++).
