[PATCH] Restore use of tr1::unordered_map in testsuite

[Jonathan Wakely]

My recent change to this file broke running the testsuite with
-std=c++98 because std::unordered_map isn't available. This fixes it.

        * testsuite/util/testsuite_abi.h: Restore use of tr1/unordered_map
        when compiled as C++98.

Tested x86_64-linux, committed to trunk.
