These tests were not being run when -D_GLIBCXX_USE_CXX11_ABI=0 was added to the test flags, but they actually work OK with the old string.
libstdc++-v3/ChangeLog: * testsuite/21_strings/basic_string/allocator/char/minimal.cc: Do not require cxx11-abi effective target. * testsuite/21_strings/basic_string/allocator/wchar_t/minimal.cc: Likewise. * testsuite/27_io/basic_fstream/cons/base.cc: Likewise. Tested powerpc64le-linux. Committed to trunk.
