If the user runs devtool add on an npm:// URL (or source tree that uses node.js), and npm is not available, just build nodejs-native instead of telling the user they need to do it; if that fails because there isn't any such recipe (which would be the default, since it's not in OE-Core) then produce a slightly more readable error message hinting at what the user needs to do. Note that this forces the use of nodejs-native rather than npm on the host - this makes sense for two reasons: (1) we need it to be compatible with nodejs for the target, and (2) we have to have a recipe for that anyway, so allowing you to avoid having a recipe for the native version isn't really beneficial. There's a bit of a hack in here in order to allow this - for node.js sources that aren't fetched via npm we don't know that they are that until we've fetched and unpacked them, by which time we're inside recipetool and have an active tinfoil instance that will prevent bitbake being run. To avoid this being an issue, we allow recipetool to get to the point where we know we need npm and then exit with a specific exit code, at which point devtool can try to build it and then if that succeeds, it will re-execute recipetool. This is definitely not ideal, but it can't really be refactored and done properly until we do the tinfoil2 refactoring; in the mean time though we still want to be helpful to the user. Fixes [YOCTO #10337].
