libgreen is not always built correctly

[am0d]

This seems to be due to the fact that libgreen is no longer a dependency of rustc - see commit 40ab198.

When I run make all on my machine, libgreen does not get built, and I'm not sure how to make it build.

Actually, on further investigation, it appears that libgreen and all the other libs have moved and now reside in a subdirectory - stage2/lib/rustlib/... - is there a reason for this change?

Closing as working as intended. The stage0/stage1 versions of libgreen are no longer built as part of the normal compilation process, but stage2 will always build all libraries.
