clang doesn't propagate attributes like "asm labels" and "visibility(hidden)" to builtins like mem{set,cpy,move} and __stack_smash_handler. So, when building with clang, instead mark those as protected visibility to get rid of the PLT relocations. We can't take the address of them then, but that's ok: it's a build-time error not a run-time error.

Add framework for resolving (pun intended) libc namespace issues, using wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here.
tests clean on i386, amd64, sparc64, powerpc, and mips64

Make index/rindex weak aliases of strchr/strrchr since they are not part of the ISO C standard and have also been dropped from POSIX. OK guenther@ kettenis@

restructure libc/string + libc/arch/*/string coperation regarding (potentially) MD versions (function dependent, not filename dependent) split out memcpy/memmove/bcopy and strchr/index/strrchr/rindex Bring back amd64 .S versions
And the final touch: switch all architectures temporarily to MI memcpy.c, which contains syslog + abort for overlapping copies. A nice harsh undefined behaviour. We will clean the entire userland of the remaining issues in this catagory, then switch to the optimised memcpy which skips the memmove check.
I tried to cut this change into pieces, but testing each sub-step on every architecture is too time consuming and mindnumbing. ok miod
