I've made attached quick hack patch for texinfo.tex.
The following command does not occur `Undefined control sequence.'
with the patch.

$ TEX=luatex PDFTEX=luatex PDFLATEX=lualatex make -j 16 CPU_COUNT=16 LANGS='' 
doc

Some other errors occur, but † U+2020 DAGGER, ‡ U+2012 DOUBLE DAGGER,
§ U+00A7 SECTION SIGN and ¶ U+00B6 PILCROW SIGN are not missing in the PDF.
However, all of the fonts in the PDF are lmroman10-regular.otf by the patch.
