[luatex] Very recent breakage luatex85.sty and cmap.sty

[Norbert Preining]

Dear all,

one of the updates that came into TeX Live between
        13 January and 2 February
has broken Sphinx document building with lualatex.

Minimal example file is:
        \RequirePackage{luatex85}
        \documentclass{report}
        \usepackage{cmap} 
        \begin{document}
          \begin{tabular}{c}
            Hello
          \end{tabular}
        \end{document}

Note that the luatex85, cmap, **and** the tabular is necessary.

The error is
        (/home/norbert/tl/2020/texmf-dist/tex/latex/base/ts1cmr.fd)<<ot1.cmap>>
        ! Undefined control sequence.
        reserved@a ...ng endcsname {pdfnobuiltintounicode 
                                                          noexpand font@name 
noexpan...
        
        l.5   \begin{tabular}
                           {c}
        ? 

I have seen the same with <<oms.cmap>> depending on font setup

Is this intended, and if not, how can it be fixed?

Thanks

Norbert
