Update version of config.guess used by ConfigureMake

[ocaisa]

The version of config.guess that we use is from 2018. Looking at https://git.savannah.gnu.org/cgit/config.git/log/config.guess it is probably important that we update it for RISC-V support

I agree we should use a more recent config.guess, but hopefully this won't lead to nasty surprises, since it will be difficult to ensure we don't introduce any regressions by doing so...

We should also use a cgit download URL, see https://git.savannah.gnu.org/cgit/config.git/commit/config.guess?id=888c8e3d5f7bf7464bba83aaf54304a956eefa60

In addition, we should check if we should also download config.sub alongside config.guess

I'm thinking about adding CONFIG_GUESS_VERSION as part of the config.guess filename. That way every version of EB will always use the same version of the file. Right now, if you we update the eb version and then someone uses an older version of eb to install something you will get an error about the checksum/dates not matching.

I looked into config.sub and according to the docs:

configure recognizes short aliases for many system types; for example, decstation can be used instead of mips-dec-ultrix4.2. configure runs a script called config.sub to canonicalize system type aliases.

It's a good bit of work to add config.sub and I don't see it having any value for us since we are getting the system type from config.guess

That's only true for the develop branch (if you go back to an old commit in develop), since there's a separate config.guess downloaded for every EasyBuild version.
