If you want all external links to do so, MediaWiki has a setting for it: $wgExternalLinkTarget. Just add the following to your LocalSettings.php:

$wgExternalLinkTarget = '_blank';

Anyway, please note that doing so forces all external links to open in new windows, which by many users is regarded to be bad behaviour.
