Why are ubsan_rt re-exports weak when they could be strong?

[kubkon]

Is there any reason why you are re-exporting symbols that appear to always be unique as .Weak instead of .Strong? Do envision them being overloadable?

const linkage: std.builtin.GlobalLinkage = if (builtin.is_test) .Internal else .Weak;

It's because the implementation is derived from: ziglang/zig#5165, and I haven't looked at that side of things myself yet to see what is appropriate. @LemonBoy is there a specific reason why the symbols are weak?
