This patch makes Zend includes its "own" set of libraries, so
that external support libs used by PHP extensions are linked once
when building PHP lib. I simply define ZEND_LIBS. I cannot tell what
impact this would otherwise have. I'm not that familiar with the PHP code.
I guess, AC_SUBST(ZEND_LIBS) has to be used in PHP's configure.in as well.
