When cross-compiling a rust package, all we need is the std library compiled for the target. This uses the final stage compiler which was built for Build and then uses that as a stage0 compiler for target std library. It also copies the rust binary from pkgsBuildBuild so that it find the new lib/rustlib directory. We also need to create a cargo wrapper which will use the "new" rust compiler Also makes sure man pages and doc pages are propagated Co-authored-by: Alyssa Ross <hi@alyssa.is> Co-authored-by: Sandro <sandro.jaeckel@gmail.com> Co-authored-by: Rick van Schijndel <Mindavi@users.noreply.github.com>
