Remove uses of -lstdc++ on darwin

This flag has been invalid seemingly since macOS 10.9 from 2013. By
default clang remaps this back to -lc++, but if your linkopts pass
-nodefaultlibs this is not the case, in which case this invalid flag
fails the link. This happened for rust builds where the rust driver
passes this flag intentionally.
