//! Large archive example.
//!
//! This creates several C files with a bunch of global arrays. The goal is to
//! create an rlib that is over 4GB in size so that the LLVM archiver creates
//! a /SYM64/ entry instead of /.
//!
//! It compiles the C files to .o files, and then uses `ar` to collect them
//! into a static library. It creates `foo.rs` with references to all the C
//! arrays, and then uses `rustc` to build an rlib with that static
//! information. It then creates `bar.rs` which links the giant libfoo.rlib,
//! which should fail since it can't read the large libfoo.rlib file.
