As reported by Randy, running make htmldocs on a machine
without textlive now produce warnings:
$ make O=DOCS htmldocs
../Documentation/Makefile:70: warning: overriding recipe for target 'pdfdocs'
../Documentation/Makefile:61: warning: ignoring old recipe for target 'pdfdocs'
That's because the code has now two definitions for pdfdocs in
case $PDFLATEX command is not found. With the new script, such
special case is not needed anymore, as the script checks it.
Drop the special case. Even after dropping it, on a machine
without LaTeX, it will still produce an error as expected,
as running:
$ ./tools/docs/sphinx-build-wrapper pdfdocs
Error: pdflatex or latexmk required for PDF generation
does the check. After applying the patch we have:
$ make SPHINXDIRS=peci htmldocs
Using alabaster theme
Using Python kernel-doc
$ make SPHINXDIRS=peci pdfdocs
Error: pdflatex or latexmk required for PDF generation
make[2]: *** [Documentation/Makefile:64: pdfdocs] Error 1
make[1]: *** [/root/Makefile:1808: pdfdocs] Error 2
make: *** [Makefile:248: __sub-make] Error 2
Which is the expected behavior.

There seems to be a related issue.
At current "docs-mw", under build environments who don't have xelatex nor latexmk,
$ make SPHINXDIRS=peci latexdocs
completes without any issue.
In the resulting .../latex/peci directory, one can run
$ make PDFLATEX="latexmk -xelatex" LATEXOPTS="-interaction=batchmode -no-shell-escape"
and build peci.pdf.
At current "build-scripts", I get this:
$ make SPHINXDIRS=peci latexdocs
Error: pdflatex or latexmk required for PDF generation
make[2]: *** [Documentation/Makefile:68: latexdocs] Error 1
make[1]: *** [<srcdir>/Makefile:1806: latexdocs] Error 2
make: *** [Makefile:248: __sub-make] Error 2
Patch 2/2 doesn't change the behavior.
This is yet another regression. Please teach sphinx-build-wrapper of the
fact that "latexdocs" does not run those texlive commands. It is only the
"pdfdocs" phase that will run them.

Akira

Sorry, a quick follow-up.

I failed to mention, but of course you need to transfer/share said
.../peci/latex/ to another build environment who has all the required
packages for "pdfdocs".
I often use such heterogeneous combination of running "make latexdocs"
+ running make under each of .../$SPHINXDIRS/latex/ using another
environment.
This way, you need only one set of working texlive packages for testing
against various Sphinx's latex builder releases.

You see, "make latexdocs" is supposed to generate all the necessary files
for building PDFs to be consumed by make + latexmk/xelatex.
There is a clear boundary between "latexdocs" and "pdfdocs".

True. This is an one-line fix:

True.
Such patch should address your usecase: it will allow building
tex files on one machine and generate pdf on a different one.
