[tlbuild] Custom-built xdvipdfmx cannot find pdftex.map on a basic-scheme TDS

[Vadim Kantorov]

I built custom xetex and xdvipdfmx (texlive.sh) into "./build" and
installed a basic-scheme TexLive distro into "./texlive" with
install-tl (latex.sh). My machine does not have a system-wide TexLive
installation.

Compiling (bug.sh) a dummy tex file produces warnings from xdvipdfmx:
xdvipdfmx:warning: Couldn't open font map file "pdftex.map".
xdvipdfmx:warning: Couldn't open font map file "kanjix.map".

I am using "./texlive/texmf-dist/web2c/texmf.cnf" as my CNF file.

It seems that the */updmap/*.map files
("./texlive/texmf-var/fonts/map/pdftex/updmap/pdftex.map" and
"./texlive/texmf-var/fonts/map/dvipdfmx/updmap/kanjix.map") are not
referred to by this CNF file and thus are not found by xdvipdfmx or
kpsewhich.

I would be very grateful if you could advise if this is my error or a
TexLive installer issue.

A full repro of all installation scripts (texlive.sh, latex.sh,
bug.sh) and error messages:

(This exercice is part of my yet-another-latex-in-browser attempt. A
Chrome-working version of xetex+bibtex8+xdvipdfmx is available at
https://vadimkantorov.github.io/busytext/busytex.html)

Thank you!
