Change Details

``` I added all the openssl functions that we call in tests.c and in bench_verify.c to the m4 check, that way if any of them are missing it won't enable openssl. I also modified it a little to prevent a segmentation fault when running that program (not that it really matters for autotools) ``` Backport of secp256k1 PR838.
