[bug#46959] [PATCH 0/1] WIP: gnu: newlib: Fix CVE-2021-3420.

[Léo Le Bouter]

newlib-CVE-2021-3420.patch needs backporting to the versions of newlib it is
being applied to, so if you are interested or a user of those packages please
finish the work, otherwise well CVE-2021-3420 will probably remain unfixed.

The versions of newlib are too old and too specific for it to be
maintainable security-wise, especially considering upstream does not seem to
maintain older versions at all. I don't think GNU Guix should take that role,
but of course the people who depend on these packages can ensure they are good
enough for themselves, otherwise contribute changes.
