Revert "kbuild: Add option to turn incompatible pointer check into error"

This reverts commit ef50c046338948df9f23fb5ef853efda0274c7b3.

So adding -Werror=incompatible-pointer-types wasn't a bad idea, but it
should really not be done in the scheduler tree: it exposes us to a
number of pre-existing warnings (most of them harmless), now upgraded
to build failures...

This should be done via the kbuild tree.
