perl path patch

[Michael Pruett]

Here's a small patch against automake 1.6.2 which allows automake to
use the copy of Perl in the user's path (which may differ from the path
with which automake was built) as long as that version is sufficiently
recent (where sufficiently recent here means Perl 5.6 or newer).
