Need a Zend karma person for PR #497

Zend karma having folks, Is there any chance someone can pull https://github.com/php/php-src/pull/497 into PHP-5.4 and PHP-5.5, please? It's a backport of a fix that's already in master to use $YACC when testing the bison version, which makes non-tarball compilation on systems with ancient bison versions in /usr easier.[0] Alternatively, if someone wants to grant me Zend karma so I can commit it myself, that would be spiffy too, since I seem to average a few of these sorts of small cleanup patches a year and having to annoy people when they happen to touch Zend specifically is annoying. :) Thanks, Adam [0] OS X, mostly. Yes, I know I can change $PATH, but it would be nice to be able to override this more specifically.
