Hi Ken.

The sanitizers are usable in contemporary Clang versions on FreeBSD
but I'm not aware of any effort on getting the GCC ones to work. I
suspect you're correct and it's just disabled by default because it's
unsupported.

I haven't compared the Clang and GCC implementations so I'm not sure
if there's a straightforward way to use the Clang one as a reference.
