Subject: [PATCH 17/17] Conditionalize test for PR libstdc++/71181 on
__LIBSTDCXX_SO_VERSION >= 7
This test was added upstream 2016-06-20 as part of:
re PR libstdc++/71181 (Reserving in unordered_map doesn't reserve enough)
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=29dbb034cb3199167a9d0aaed040733c72326eed
but fails when run in DTS against a system libstdc++.so from an older GCC.
