libstdc++: Remove -gdwarf-4 from flags for debug library

The default is -gdwarf-5 now, so this is hurting rather than improving
things.

libstdc++-v3/ChangeLog:

	* configure.ac (GLIBCXX_ENABLE_DEBUG_FLAGS): Remove -gdwarf-4
	from default flags.
	* configure: Regenerate.

(cherry picked from commit fe3e978027724f28d3e15747c991844793d42922)
