Comment:

 The check for functions is happening before it has figured out how to link
 libevent, but it still works(ish) by accident.

 Other platforms are happy enough with -levent so they find (or don't find)
 the functions, and the function check fails on OpenBSD because it can't
 link it, so everyone gets (almost) the right result.

 Although, on OpenBSD it also fails to find
 evutil_secure_rng_set_urandom_device_file() which is available.
