Before CL 8214 (use .plt instead of .got on Solaris) Solaris used a dynamic linking scheme that didn't permit lazy binding. To speed program startup, Go binaries only used it for a small number of symbols required by the runtime. Other symbols were resolved on demand on first use, and were cached for subsequent use. This required some moderately complex code in the syscall package. CL 8214 changed the way dynamic linking is implemented, and now lazy binding is supported. As now all symbols are resolved lazily by the dynamic loader, there is no need for the complex code in the syscall package that did the same. This CL makes Go programs link directly with the necessary shared libraries and deletes the lazy-loading code implemented in Go.
