- Implement PT_INTERP, and thus dynamic linking. · 049a5156
  Jacob Lorentzon authored 2 years ago
  
  With this change, gcc can now successfully compile a tiny program that printfs an integer returned from a function, from a dynamically linked library that it compiled as well. Rustc however, is orders of magnitude more complex, and the next step is to fix constructors which require access to `environ`, in ld.so

- Conflict-proof #[global_allocator] symbols too. · 3701ea3b
  Jacob Lorentzon authored 2 years ago
  
  The #[global_allocator] used by relibc is only relibc's business. Symbols should therefore not leak if another applications for example wants to override the system allocator (and for bootstrap, which links to relibc but uses its own #[global_allocator] based on libc functions).

- Allow POSIX's `environ` to be set. · c95d276a
  Jacob Lorentzon authored 2 years ago
  
  Rust's libstd for example uses environ when using the `envs` builder method for spawning processes, and therefore relibc cannot simply assume environ will always point to the internal relibc env var Vec.
