Here is another variant of potential interest. In this version, in addition to adding putting the host rpath setting onto the $DYLD_LIBRARY_PATH, it also tells rustdoc to look in that directory for its own lookups, via rustdoc's -L option.

The main point I'm making here is that this tells us where rustdoc is forcibly adding to its own library lookup path, despite the settings of the DYLD_LIBRARY_PATH, as you can see by looking at duplicate entries during the inspection of the dylib candidates.

% echo $DYLD_LIBRARY_PATH

% DYLD_LIBRARY_PATH="$DYLD_LIBRARY_PATH:/Users/fklock/Dev/Mozilla/rust-fixstage1/objdir-check1-dbgopt/x86_64-apple-darwin/stage1/lib" x86_64-apple-darwin/stage1/bin/rustdoc --test /Users/fklock/Dev/Mozilla/rust-fixstage1/src/libstd/lib.rs --test-args "bitxor" -L /Users/fklock/Dev/Mozilla/rust-fixstage1/objdir-check1-dbgopt/x86_64-apple-darwin/stage1/lib
