    lang/gcc12: 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.

+Since the vDSO shared librares on Linux and FreeBSD are called
+differently, the initialization order check fails on FreeBSD.
+This patch fixes it by ignoring [vdso] instead of linux-vdso.so.
+
+GCC gets the original file from the LLVM Project, so this patch should
+probably be upstreamed directly to the LLVM Project rather than to GCC.
