build: Skip step that checks for C++11 flags during configuration (bug #65327). * configure.ac: Use (un-documented) workaround to skip autotools test for compiler flags that enable C++11 support. That test is broken for compilers that are C++20-compliant.

305 # AC_PROG_CXX attempts to find the compiler flags for activating support for
306 # C++11. As of autoconf version 2.71, the source code that it uses for that
307 # test includes parts that are invalid in C++20.
