<https://gcc.gnu.org/ml/libstdc++/2016-08/msg00006.html> arranged for libstdc++ tests to use -fno-show-column by default, but only for build-tree testing. This patch adds it to the options used for installed testing as well.
Tested with installed testing for a cross to x86_64-linux-gnu, where it fixes various test failures. 2018-10-02 Joseph Myers <jos...@codesourcery.com> * testsuite/lib/libstdc++.exp (libstdc++_init): Use -fno-show-column in default cxxflags.
