[ELF] Don't crash when parsing a file with external version definition references Summary: We were crashing when linking telnetd in FreeBSD because lld was emitting corrupted output files for --norosegment. In this file the version index of some symbols was set to 9 but lld only found 8 version definitions. I am not sure how to create a minimal .so file that also exposes this behaviour so I just added the one that initially caused the error to Inputs/ This partially addresses https://bugs.llvm.org/show_bug.cgi?id=34705 Reviewers: ruiu, rafael, pcc, grimar Reviewed By: ruiu Subscribers: emaste, krytarowski Tags: #lld Differential Revision: https://reviews.llvm.org/D38397 llvm-svn: 315035

Handle a VersymIndex of 0 as an error. I noticed that the continue this patch deletes was not tested. Trying to add a test I realized that we never put a VER_NDX_LOCAL symbol in the dynamic symbol table. There doesn't seem to be any reason for a linker to use VER_NDX_LOCAL for a defined shared symbol. llvm-svn: 320817
