Convert a use of Config->Static. In lld this was the only use of Config->Static where it meant anything else other than "use .a instead of .so". If a program turns out to not use any dynamic libraries, we should produce the same result with and without -static. llvm-svn: 324421

// REQUIRES: x86
[lld] Allow rel iplt symbols with dynamic symbol table Emit these symbols as long as we're building in a static configuration, even if we're emitting a dynamic symbol table. This is consistent with both bfd and gold. Ordinarily, the combination of -static and -export-dynamic wouldn't make much sense. Unfortunately, cmake versions prior to 3.4 forcefully injected -rdynamic [1], so it seems worthwhile to support.
