Merge configure.ac from gcc project
To merge with gcc's copy of configure.ac we need to revert changes to configure.ac in the following gcc commits: dc832fb39fc0 2022-08-25 fc259b522c0f 2022-06-25 Then reapply configure.ac changes in binutils from these binutils commits: 50ad1254d503 2021-01-09 bb368aad297f 2022-03-11 e5f2f7d901ee 2022-07-26 2cac01e3ffff 2022-09-26 Plus copy over gcc's config/ax_cxx_compile_stdcxx.m4, then regenerate configure.
