[PATCH] maint: avoid perl warning in sc_check-AUTHORS

[Bernhard Voelker]

On openSUSE-13.1 with perl v5.18.1, I was getting many warnings during
syntax-check:

  check-AUTHORS
  -i used with no filenames on the command line, reading from STDIN.
  -i used with no filenames on the command line, reading from STDIN.
  ...
  -i used with no filenames on the command line, reading from STDIN.
  0.94 check-AUTHORS

The following patch fixes it.

Have a nice day,
Berny

Subject: [PATCH] maint: avoid perl warning in sc_check-AUTHORS

With newer perl, "make syntax-check" issues many warnings like:
  -i used with no filenames on the command line, reading from STDIN.

* cfg.mk (sc_check-AUTHORS): Remove the -i flag in the perl
invocation as it is reading from a pipe.
