28.1: errors about missing git executable

28.1: errors about missing git executable

[Óscar Fuentes]

While building 28.1 from the source tar package I see lots of mentions
to missing git:

    ELN  ../../emacs-28.1/lisp/tooltip.eln
    ELN  ../../emacs-28.1/lisp/uniquify.eln
  Error: (file-missing "Searching for program" "No such file or directory" "git")
  Error: (file-missing "Searching for program" "No such file or directory" "git")

...


  Loading leim/leim-list.el (source)...
  Waiting for git...
  Error running git rev-parse: (file-missing "Searching for program" "No such file or directory" "git")
  Waiting for git...
  Error running git rev-parse --abbrev-ref: (file-missing "Searching for program" "No such file or directory" "git")
  Finding pointers to doc strings...

The build goes along, but I wonder why those messages are shown and if
they have an effect on the build products.

The last two messages (about git rev-parse) are harmless (they are
inside ignore-errors), but those emitted by ELN are not expected, I
think.  A Lisp backtrace for those errors should be useful.

Actually, a full-fledged bug report with all the details, including
how you configured the build, would be appreciated.
