    libc++: avoid use of deprecated __reference_binds_to_temporary
    
    This was removed in upstream libc++ in commit
    437ad06f762ab07d89badecdd20627db200b98d3, but as this does not apply
    cleanly to the current repository, I am applying the equivalent change
    in a minimally invasive way. This is needed to build with latest clang
    HEAD as of today.
