This patch seems to break detection of EVP_aes_128_ctr() while building
against OpenSSL. This is the corresponding part of config.log with the
current master branch:
configure:16982: checking for EVP_aes_128_ctr
configure:16982: gcc -o conftest -g -O2 conftest.c -lssl -lcrypto >&5
configure:16982: $? = 0
configure:16982: result: yes
But with this patch applied, it looks like this:
configure:14772: checking for EVP_aes_128_ctr
configure:14772: gcc -o conftest -g -O2 conftest.c >&5
/tmp/ccARmUY4.o: In function `main':
conftest.c:60: undefined reference to `EVP_aes_128_ctr'
collect2: error: ld returned 1 exit status
configure:14772: $? = 1
