Don't use '-z defs' if sanitizers are used

There are quite a number of sanitizers for clang that aren't
documented in the clang user documentation.  This makes it impossible
to be selective about what sanitizers to look at to determine if
'-z defs' should be used of not.

Under these circumstances, the sane thing to do is to just look for
any sanitizer specification and not use '-z defs' if there's one
present.

Fixes #8735
