The clang documentation in all sanitizers we currently use says this:
When linking shared libraries, the {flavor}Sanitizer run-time is
not linked, so -Wl,-z,defs may cause link errors (don’t use it
with {flavor}Sanitizer)
(in our case, {flavor} is one of Address, Memory, or UndefinedBehavior)
Therefore, we turn off that particular flag specifically when using
the sanitizers.
Fixes #8735
