* add `zig libc` command * add `--libc` CLI and integrate it with Module and linker code * implement libc detection and paths resolution * port LLD ELF linker line construction to stage2 * integrate dynamic linker option into Module and linker code * implement default link_mode detection and error handling if user requests static when it cannot be fulfilled * integrate more linker options * implement detection of .so.X.Y.Z file extension as a shared object file. nice try, you can't fool me. * correct usage text for -dynamic and -static
