Subject: [PATCH 1/2] replace "perl -w" with "use warnings"

The shebang's max length is usually 128 as defined in
/usr/include/linux/binfmts.h:
  #define BINPRM_BUF_SIZE 128

There would be errors when @PERL@ is longer than 128, use
'/usr/bin/env perl' can fix the problem, but '/usr/bin/env perl -w'
doesn't work:

/usr/bin/env: perl -w: No such file or directory

So replace "perl -w" with "use warnings" to make it work.

Upstream-Status: Pending

Signed-off-by: Robert Yang <liezhi.yang@windriver.com>

Rebase to 1.22.4.
