Software compiled with -fsanitize=address fails to run with the error message "ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD". This commit fixes the issue by ignoring the [vdso] loaded shared library instead of linux-vdso.so. PR: 267751 Reported by: yuri Co-authored-by: Andreas Tobler <andreast@gcc.gnu.org>
