bug#10448: dist-xz and dist-gzip cannot be combined?

[Ludovic Courtès]

Hi,

The ‘master’ branch of Automake fails to produce both a tar.gz and
tar.xz tarball.  The former is empty, apparently because the source tree
gets removed after the tar.xz is created:

--8<---------------cut here---------------start------------->8---
tardir=automake-1.11a && ${TAR-tar} chof - "$tardir" | XZ_OPT=${XZ_OPT--e} xz 
-c >automake-1.11a.tar.xz
{ test ! -d "automake-1.11a" || { find "automake-1.11a" -type d ! -perm -200 
-exec chmod u+w {} ';' && rm -fr "automake-1.11a"; }; }
atardir=automake-1.11a && ${TAR-tar} chof - "$tardir" | GZIP=--best gzip -c 
>automake-1.11a.tar.gz
tar: automake-1.11a: Cannot stat: No such file or directory
tar: Exiting with failure status due to previous errors
--8<---------------cut here---------------end--------------->8---

(This is from the ‘tarball’ job at
<http://hydra.nixos.org/jobset/gnu/automake-master>.)

Thanks,
Ludo’.
