The c++tools configure fragments need to be built with a C++ compiler.
In addition, the stand-alone server uses diagnostic mechanisms in common
with GCC, but needs to define implementations for gcc_assert and
supporting output functions.

This TU uses exit, but doesn't include <stdlib.h> or <cstdlib> and relies
on some other header to include it indirectly, which apparently doesn't
happen on reporter's host.
The other <c*> headers aren't guarded either and we rely on a compiler
capable of C++11, so maybe we can rely on <cstdlib> being around
unconditionally.

It appears that many targets include the map header transitively in
other std headers included from system.h. However there are some
editions of clang/libc++ in Xcode that do not, which results in a
bootstrap fail - since when resolver.h is included there is then a
conflict in declaring abort().
The fix is to ensure that map is pulled in by system.h and before
resolver.h is included. As a precautionary measure and to alert
anyone perhaps adding another header to resolver.h this patch also
gates the direct includes there on !IN_GCC.

building in GCC.

PR98318 also pointed out that the NETWORKING #define was being checked

With the introduction of C++20 modules and libcody, cc1plus and
cc1objplus gained a dependency on the socket functions. Before those
were merged into libc in Solaris 11.4, one needed to link with -lsocket -lnsl
on Solaris, so that merge broke the Solaris 11.3 build.
While we already have 4 different checks for those libraries in the
tree, I decided to import autoconf-archive's AX_LIB_SOCKET_NSL macro
instead. At the same time, the patch only links libcody and the
networking libs where needed (cc1plus, cc1objplus).
Bootstrapped without regressions on i386-pc-solaris2.11 (Solaris 11.3
and 11.4), sparc-sun-solaris2.11, and x86_64-pc-linux-gnu.

I had a thinko about variable case, and, coupled with Make's behaviour
of just consing up variables out of nothing, and linux not having an
executable extension, didn't notice.

When breaking out the sample server from the gcc/cp directory, it lost
its check for mmap, and the sample resolver just assumed it was there.
Fixed thusly. The non-mapping paths in module.cc weren't (recently)
excercised, and led to a signedness warning. Finally I'd missed
c++tools's config.h.in in the gcc_update script. There I took the
opportunity of adding a 'tools' segment of the dependency lists.

Seems c++tools doesn't honor --with-gcc-major-version-only.
Our distro uses that flag and so everything is installed in
/usr/lib/gcc/<target>/11/...

except

Part of our module implementation adds a sample mapper server, the
guts of which are used by the default in-process mapping of cc1plus.
Rather than add another executable to gcc/cp/, this creates a new
c++tools directory where this and any other c++ tools might live.
The toplevel changes are a subsequent commit, because ... git.
