build: don't accept a broken standard lib for C++
On the CI, we had failures such as:
./c++.at:401: $PREPARSER ./list
stderr:
./list: error while loading shared libraries: libc++.so.1:
cannot open shared object file: No such file or directory
because we accepted `-std=c++ -stdlib=libc++` although libc++ is not
installed on the machine.
* m4/ax_check_compile_flag.m4 (AX_CHECK_COMPILE_FLAG): Rewrite as...
* m4/bison-check-compile-flag.m4 (BISON_CHECK_COMPILE_FLAG): this, so
that we use AC_LINK_IFELSE to check the compiler (and its std lib)
instead of AC_COMPILE_IFELSE.
