Do not allocate space for common symbols with -r Currently ld.lld -r allocates space for common symbols, whereas ld.bfd -r doesn't. As a result the OpenBSD makefile bits for creating libraries fail as they use ld -X -r to strip local symbols, which results in duplicate symbol errors because space for the common symbols has been allocated. The diff also implements the --define-commons option such that allocation of commons can be forced even if -r is used. Patch by Mark Kettenis. llvm-svn: 292878
