With --enable-dtrace, the correct PIC/non-PIC .o files on Solaris and

Linux are now used.  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!
