It looks like our check-performance target runs completely unoptimized,
which is a bit silly. This exports the CXXFLAGS from the parent make
process to the check_performance script.
libstdc++-v3/ChangeLog:
* scripts/check_performance: Use gnu++11 instead of gnu++0x.
* testsuite/Makefile.am (check-performance): Export CXXFLAGS to
child process.
* testsuite/Makefile.in: Regenerate.
Tested powerpc64le-linux. Committed to trunk.

libstdc++: Pass CXXFLAGS to check_performance script
