History
Dimitry Andric 867a1d621d [sanitizer_common] mark __elf_aux_vector as weak on FreeBSD (#118110) 
At some point FreeBSD introduced libsys as a wrapper between syscalls
and libc, and then linking sanitized programs started failing with:

```text
  # c++ -fsanitize=address main.cc
  ld: error: undefined symbol: __elf_aux_vector
  >>> referenced by sanitizer_linux_libcdep.cpp:950 (/usr/src/contrib/llvm-project/compiler-rt/lib/sanitizer_common/sanitizer_linux_libcdep.cpp:950)
  >>>               sanitizer_linux_libcdep.o:(__sanitizer::ReExec()) in archive /usr/lib/clang/17/lib/freebsd/libclang_rt.asan-x86_64.a
  c++: error: linker command failed with exit code 1 (use -v to see invocation)
```

Mark `__elf_aux_vector` as weak in the internal sanitizer declaration,
so the linker will accept it at link time. The dynamic linker will then
take care of the symbol at run time.
