This sounds great to me, but I cannot approve it. I hope some of the
people who can will comment on it.

One thing that I miss is documenting gnulib in doc/sourcebuild.texi.
It would be good to document in particular how to add a new module.
GDB has: https://sourceware.org/gdb/wiki/DeveloperTips#Updating_GDB.27s_import_of_gnulib
but I think this info should be in sourcebuild.texi (or somewhere else
under doc/).

 I see several other mentions of libiberty in doc/, but some of them
may be just using libiberty as an example, thus not relevant.

Cheers,

Manuel.
