Zig: Proposal: option to allow syscalls at comptime

[bazzb]

There should be an option to explicitly allow certain packages to make syscalls at comptime

[EleanorNB]

What would be the use cases for this?

Mostly because it is nicer than doing it in the build.zig, putting it in a file and then embedding that file.
I understand it is probably for safety but i think it would be fine if we make it explicitly allowable.

Far more than just safety:

• it requires knowledge about host structures and layouts instead of target structures and layouts (in zig, cross compiling is a top priority)
• it runs counter to zig's caching strategy (as interacting with the outside environment as syscalls do cannot be cached).
