I have only added some AArch64 I think the same principle applies for ports to new (architecture, Hurd) pairs as for new (architecture, Linux) pairs: the relevant code needs to be in upstream mainline of all components on which glibc build-depends before the port can go into glibc (and thus before the symbol versions for the port can be determined) - and at the point where it's ready to go in, a corresponding build-many-glibcs.py entry should be added as part of the patch series. Parts of <https://sourceware.org/glibc/wiki/NewPorts> may be applicable, though that's more oriented to the case where the architecture support itself is entirely new. You can of course do refactors of existing files not specific to aarch64-gnu, in preparation for the port, before then, to reduce the size of the eventual patch series proposing adding the port to glibc. -- Joseph S.
