Explicitly document that the jobserver may be used by `rustc` and show the warning to increase the chances that this document is found when searching for solutions online. In particular, add a section about the interaction with build systems, which is intended to contain recommendations on how to integrate `rustc` with different built systems. For GNU Make, recommend using the `+` indicator. In addition, add a note about the issue with GNU Make 4.3 since it is important that users realize they should do this even if they do not expect parallelism from `rustc`. Finally, show how to workaround the issue of `$(shell ...)` calls in recursive Make (which e.g. was needed for the Linux kernel). The GNU Make 4.4 case under `--jobserver-style=pipe` is not added since it got fixed after Rust 1.76.0 already (i.e. `rustc` will not warn if it finds the negative file descriptors). For CMake, recommend using `JOB_SERVER_AWARE` and show a workaround using `$(MAKE)` for earlier versions (when using the Makefile generator).
