No, because they are not needed for the bootstrapping itself. We build 
stuff from scratch for it, I needed them to rebuild the configure 
scripts on GCC, which I don't need to rebuild anymore (GCC's codebase 
includes the configure scripts prebuilt). That's where I realized.

I don't know either. I tried to use the 2.64 one and that told me the 
Automake wasn't compatible.

The problem in my opinion is including a 2.64 autoconf that we can't run 
actually use for the lack of a compatible automake. Not providing it is 
a better option. I don't need it for bootstrapping recipes, and if I 
need it in the future I'll remake the package.

If Autoconf 2.64 is not needed by any package my proposal is to remove 
it from Guix and let the people interested on it to `time-machine`, as 
that's going to probably have the correct automake with it.

Thank you!
