    lang/gcc13: Fix Address sanitizer

    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.

    To successfully run the software compiled with -fsanitize=address it is
    still necessary to disable ASLR.
