Experimental hack, not expected to be merged. Without this, the http://www.cplusplus.com/reference/string/string/append/ example fails to build with -std=c++11 and it's not clear why (it's as if we build a version of libstdc++ which supports only the old ABI but with headers which try to use the new ABI when compiled with -std=c++11 ?). As a workaround, force libstdc++ to provide, and default to using, the old ABI in all cases.
