DTrace is part of Oracle Linux. See https://oss.oracle.com/projects/DTrace/ This patch does not change DTrace linking for non-Solaris/Linux platforms. For SystemTap users on Linux, this patch removes the compilation warning: Warning: Linking the shared library libphp5.la against the non-libtool objects Zend/zend_dtrace.d.o is not portable!
