build: make passing an incorrect pointer type a hard error
More or less any of this issue pointed out by the compiler is
a coding error. Make sure we flag it and bail loudly.
v2: - apply the change to autotools and scons as well (Emil)
- C++ doesn't need this, it's already an error and the flag
doesn't exist (Gert)
v3: - drop scons, flags are not checked so until someone adds that
functionality we can't have this.
