Avoid possible crash within libsanitizer. We've successfully used libsanitizer for awhile with the undefined and alignment sanitizers, but with some other sanitizers (at least thread and hwaddress) it crashes due to internal recursion before it's fully initialized itself. It turns out that that's due to the "__ubsan_default_options" hack installed by commit f686ae82f, and we can fix it by ensuring that __ubsan_default_options is built without any sanitizer instrumentation hooks.
