I think this is unhygienic. It is surprising to me that building something would cause files to be added to my home directory. This also breaks when building in a sandboxed environment (which is how I found out).

Plus, it is downloading something that is not strictly needed for the build process. And it is also not going to achieve what I assume is your goal. What if I build on one machine then ship the binary to run somewhere else?
