This commit does three things: * First, it passes --cfg=bootstrap on stage 0 for rustdoc invocations on proc_macro crates. This mirrors what we do already for rustc invocations of those, and is needed because cargo doesn't respect RUSTFLAGS or RUSTDOCFLAGS when confronted with a proc macro. * Second, it marks the bootstrap config variable as expected. This is needed both on later stages where it's not set, but also on stage 0, where it is set. * Third, it adjusts the comment in the rustc wrapper to better reflect the reason why we set the bootstrap variable as expected: due to recent changes, setting it as expected is also required even if the cfg variable is passed: ebf4cc3 .
