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.

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.

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.
