For today's FreeBSD 14 and earlier, libssp is a nop because nothing on
FreeBSD will be referencing these headers or lib. On FreeBSD 15, it
actively breaks building with FORTIFY_SOURCE enabled and it's not worth
trying to make it work- the potential for GCC improvements comes from
the __builtin_object_size enhancement, not from these headers.

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.

When more recent gcc ports are built without bootstrap, compiling libcc1
plugins results in errors similar to:

This is because gcc's own system.h header poisons these identifiers, and
the libcc1 plugins include <vector> after that. (Note that libstdc++ is
not affected because they seem to have implicitly included <vector>
already at that point.)
Fix it by telling system.h to include <vector> at the correct place, and
removing the explicit includes from libcc1plugin.cc and libcp1plugin.cc.
