[PATCH] scripts/archive-source: Use more portable argument with tar command

[PATCH] scripts/archive-source: Use more portable argument with tar command

[Philippe Mathieu-Daudé]

When using the archive-source.sh script on Darwin we get:

  tar: Option --concatenate is not supported
  Usage:
    List:    tar -tf <archive-filename>
    Extract: tar -xf <archive-filename>
    Create:  tar -cf <archive-filename> [filenames...]
    Help:    tar --help

Replace the long argument added by commit 8fc76176f6 ("scripts: use
git-archive in archive-source") by their short form to keep this
script functional.

'-c' is not the short-form option of '--concatenate': that would
be '-A'. The problem is not long vs short options, but that
BSD-style tar does not support the --concatenate functionality at all.

I'm not sure that is correct. The gnu shortform for --concatenate is -A,
-c is specifically create so I suspect you end up re-creating the
tarball rather than adding to it.

Or install a better tar implementation from brew ?

Good idea, this works for me:
