Subject: [PATCH] PR78968 add configure check for __cxa_thread_atexit in libc
Authentication-results: sourceware.org; auth=none

FreeBSD 11 adds __cxa_thread_atexit to libc, so we should use that
instead of defining our own inferior version. This also avoids
multiple definitions of the symbol.

	PR libstdc++/78968
	* config.h.in: Regenerate.
	* configure: Likewise.
	* configure.ac: Check for __cxa_thread_atexit.
	* libsupc++/atexit_thread.cc [_GLIBCXX_HAVE___CXA_THREAD_ATEXIT]:
	Don't define __cxa_thread_atexit if libc provides it.

Tested powerpc64le-linux, committed to trunk.
