Autoconf has a builtin check to try figure out how to make the compiler
error out on implicit function declarations. This check necessarily emits such a warning/error. We know that -Werror=implicit-function-declaration
will work on any compiler we care about, so just force that to avoid noise.
This means we don't have to try whitelist 'strchr'.
