[PATCH] D13244: [ELF2] - implemented --allow-shlib-undefined/--no-allow-shlib-undefined

[Rui Ueyama via llvm-commits]

The GNU linker's behavior of trying to resolve all undefined symbols in DSOs looks broken in the first place. This is a linker and not a dynamic linker nor loader, it can just leave undefined symbols in DSO for the dynamic linker. LLVM itself, for example, always sets --allow-shlib-undefined to "[W]ork around a broken bfd ld behavior" (CMakeList.txt in the toplevel directory). In my opinion, we should just implement --allow-shlib-undefined behavior as default and ignore that option.
