Subject: [PATCH] perl: Replace -w option in shebangs with modern "use
 warnings" In some builds we might provide ac_cv_path_PERL as /usr/bin/env
 perl to use newer version of the perl from users PATH rather than older from
 standard system path.

However using /usr/bin/env perl -w from shebang line isn't
possible because it translates to something like
/usr/bin/env -w perl and env complains about illegal option.

To address this we can remove -w option from perl shebang
line and add "use warnings" statement.
