Jonathan Wakely 7e7eef2a1b libstdc++: Pass CXXFLAGS to check_performance script
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.
