Need "usertool" target for make

[Yngve Svendsen]

I am currently sweating over the documentation for installing GNATS user 
tools on remote machines, so that the tools can access gnatsd directly over 
the network.

In my opinion, the logical strategy for this looks something like this:

- On the client machine, download and untar GNATS. Run "./configure"
- Run "make usertools". This would build all the tools required on client 
machines, roughly corresponding to the tools currently built by the targets 
send-pr in send-pr/Makefile and tools-all in gnats/Makefile.
- Run "make install-usertools". This would install the tools built by the 
make above and copy a default send-pr.conf file to /usr/local/etc/gnats.
- Edit send-pr.conf to fit local needs and add a proper GNATSDB variable 
setting to user's environments.

I am unable to find anything resembling the targets "usertools" and 
"install-usertools" outlined above in the current master Makefile, but I 
don't think adding this would be a lot of work. However, I am not 
sufficiently experienced with makefiles to do this myself.

An alternative would be to add a --tools-only option to configure. I don't 
know what solution would be the best, but we really need to have a way to 
install the user tools on client machines before GNATS 4 can be said to be 
complete.
