[O] org master: make fails

[Julius Dittmar]

Hi,

on two of my computers, both openSUSE-based with org-mode current master
and current texlive installed, make fails.

The last messages are:

make -C doc info
make[1]: Entering directory `/XXX/git/org-mode-CURRENT/doc'
emacs  -Q -batch --eval '(setq vc-handled-backends nil
org-startup-folded nil)' \

  --eval '(load "../mk/org-fixup.el")' \
  --eval '(org-make-manuals)'

... followed by a long mainly empty and unreadable quoted string,

make[1]: *** [org.texi] Fehler 255

make: *** [info] Fehler 2

As on the third of my computers (with an old debian and texlive 2017)
make works, I guess that's a local problem, not one of org-mode.
Nonetheless: Do you have any hints on what might be missing there, or
how I could proceed tracking down the problem?

Thanks in advance,
Julius
