Hi devel team,


FYI:
Latest emacs-git from HEAD f2d22273599f96a731e23b2f6d7571af8bb7bb3f
fails to build inside an nspawn clean and updated archlinux chroot, with
this missing libgnu.a error:

...
  GEN      time.h
  GEN      unistd.h
  AR       libgnu.a
ar: fcntl.o: No such file or directory
make[1]: *** [Makefile:103: libgnu.a] Error 1
make: *** [Makefile:410: lib] Error 2
==> ERROR: A failure occurred in build().
    Aborting...
```

Full build log can be found here:
- attached to this email
- https://gitlab.com/snippets/1843871
- https://gist.github.com/stefancocora/743cc3e1f5c2a7baa484c4666ce30a58

The build is automated using this archlinux PKGBUILD package manifest
- https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=emacs-git
- attached to this email

As far as the archlinux package content search is able to find only
"extra/clisp" contains this libgnu.a file but even when adding clisp to
the depends list emacs-git fails to build.

Note:
emacs-git cf6950366bd2b2aad4daa2d601bd8ccdb50df700 has been able to
build fine using the same archlinux nspawn clean chroot and the same
PKGBUILD 2-3 weeks ago.


Regards,
Stefan
