For 0001, could we just replace configure's dlopen check with the
dlsym check? Or are you afraid of reverse-case failures?

0002: ugh, but my only real complaint is that __ubsan_default_options
needs more than zero comment. Also, it's not "our" getenv is it?

0003: OK. Interesting though that we haven't seen these before.

0004: no opinion
