    Add "-Wl,--enable-new-dtags" to linker
    
    Without RUNPATH in .dynstr section in perl binary, tested perl will
    link against old library and not only it will test old library,
    it will crash probably too.

 - Run tests in parallel
+- Add "-Wl,--enable-new-dtags" to linker to allow to override perl's rpath by
+  LD_LIBRARY_PATH used in tests. Otherwise tested perl would link to old
