With GCC 6 when not using -static-libstdc++, the operator delete(void*)
function is defined in the shared C++ support library, rather than in
the main program. The test script is too aggressive in checking for
this symbol's presence among the exported symbols. This patch removes
the check for that symbol.

* testsuite/dynamic_list.sh: Remove check for _ZdlPv.
GCC 6 does not generate constructors for two of gold's test cases.
This patch simply removes the checks for them.
