debug/gdb: install gdbinit sample file

gdb needs to know where to find the libstdc++ helper python script
to do, well, whatever it has to do with it...

We can't install that in the user's ~/.gdbinit, it's too complex to
handle all the cases. Moreover, if the user is using more than one
toolchain, we can't put all that stuff in there...

Just provide a sample config file the user can adapt to his/her
own needs.

Thanks go to Khem RAJ for providing such a hint:
