[bug#41637] [PATCH] gnu: Add hashcash.

[Mathieu Othacehe]

Hello Jakub,

It would be better to use "cc-for-target" here. You can check if
cross-compilation works by running something like:

--8<---------------cut here---------------start------------->8---
guix build --target=aarch64-linux-gnu hashcash
--8<---------------cut here---------------end--------------->8---

Thanks,

Mathieu
