Oh, sure, maybe. Perhaps "necessary steps" was an overclaim.
"Sufficient steps," then.
If you build LLVM for multiple targets at once, I have no idea what
the directory structure ends up looking like, and so all of the parts
where I'm repairing paths in the build system are probably wrong-ish.
(But since the target version of LLVM doesn't change very frequently,
even if you end up spending extra time compiling, you can amortize it
over your future rust builds.)
