Re: system-wide gpr files live in /usr/share but mention an?arch-dependant path

[Nicolas Boulenguez <nicolas.boulenguez@free.fr>]

I would suggest a name less generic than directories.gpr. An end-user
may, for very similar reasons, have a project named directories.gpr in
the current directory, and this would cause obscure errors. Something
like system_library_directories.gpr?

Once the changes are decided, we would

need to modify the part of dh-ada-library generating the installed
project and package dependencies, and build-depending packages should

need a recompilation.
