@bazel_tools//tools/cpp:malloc is equivalent and comes from https://bazel.build/reference/be/c-cpp#cc_binary.malloc. This also avoids some confusion in the documentation, since while system_malloc _can_ be used with `malloc`, it has no effect when it's used with `--custom_malloc`. But, rather than trying to adjust that, maybe we can just use @bazel_tools//tools/cpp:malloc
