Erico Nunes 9687e7435b perl: update cnf/config.{sub, guess} using autotools hook
perl may fail to build on newer host architectures such as aarch64 due
to its inability to guess the host architecture to build 'miniperl',
which is built during the process. An error message looks like this:

  Configuring build-time miniperl for unknown
  ERROR: No $target defined (?!)
  ERROR: configure --mode=buildmini failed

This happens because the config.sub and config.guess files from perl are
not modified and may become outdated.
These files are normally updated automatically by a Buildroot hook for
autotools packages, to avoid problems like these.
Although perl uses the config.sub and config.guess files, it is not a
strict autotools package, so it is not defined as an "autotools-package"
in Buildroot and so it doesn't inherit the hook.
This commit makes perl borrow the hook from the autotools infrastructure
so that it can build on newer build architectures.
This has been tested by building it on an aarch64 host machine.
