    ld: yet another PDB build fix (or workaround)
    
    Older bash looks to improperly deal with backslashes in here-documents,
    leaving them in place on the escaped double quotes inside the parameter
    expansion. Convert to a model without using such a construct, by simply
    splitting the here-documents into three ones.
