Lancelot Six f74dc26792 gdb/gdbsupport/gdbserver: Require c++17 
This patch proposes to require a C++17 compiler to build gdb /
gdbsupport / gdbserver.  Before this patch, GDB required a C++11
compiler.

The general policy regarding bumping C++ language requirement in GDB (as
stated in [1]) is:

    Our general policy is to wait until the oldest compiler that
    supports C++NN is at least 3 years old.

    Rationale: We want to ensure reasonably widespread compiler
    availability, to lower barrier of entry to GDB contributions, and to
    make it easy for users to easily build new GDB on currently
    supported stable distributions themselves. 3 years should be
    sufficient for latest stable releases of distributions to include a
    compiler for the standard, and/or for new compilers to appear as
    easily installable optional packages. Requiring everyone to build a
    compiler first before building GDB, which would happen if we
    required a too-new compiler, would cause too much inconvenience.

    See the policy proposal and discussion
    [here](https://sourceware.org/ml/gdb-patches/2016-10/msg00616.html).

The first GCC release which with full C++17 support is GCC-9[2],
released in 2019[3], which is over 4 years ago.  Clang has had C++17
support since Clang-5[4] released in 2018[5].

A discussions with many distros showed that a C++17-able compiler is
always available, meaning that this no hard requirement preventing us to
require it going forward.
