Well, sure it only worked by accident, but it did work with older
OpenSSL versions. If we assume that BIO_get_app_data exists, and
somebody tries to use it with a version that hasn't got that,
it won't work.
Having said that, my concern was mainly driven by the comments in
configure.ac claiming that this was an OpenSSL 1.1.0 addition.
Looking at the relevant commits, 593d4e47d and 5c6df67e0, it seems
that that was less about "the function doesn't exist before 1.1.0"
and more about "in 1.1.0 we have to use the function because we
can no longer directly access the ptr field". If the function
does exist in 0.9.8 then I concur that we don't need to test.
