Tom Lane c775bf048a 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.
