[Bug other/107634] Very long filenames and URLs for sphinx-based docs

["marxin at gcc dot gnu.org" <gcc-bugzilla@gcc.gnu.org>]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107634

--- Comment #7 from Martin Liška <marxin at gcc dot gnu.org> ---
So first to the original issue reported by David. Yes, the filenames were
selected based on chapter's caption and thus some of them are very long. For
gcc documentation, I'm suggesting following name scheme where the entire path
since base folder (gcc/doc/gcc) should be at maximum 50 characters w/o .rst
