autoconf: Dont execute perl and m4 for target builds

* configure decides to probe perl verison
  dont do that as it wont work when building
  target autoconf. So far it was executing /usr/bin/perl
  and /usr/bin/m4 which is found on most build machines
  however micro change the layout and /bin/perl and /bin/m4
  is now not found. So it brought up a hidden bug.
