Subject: [PATCH 1/1] configure.ac: detect ssl need with libcurl
Message-ID: <1443122040-14189-1-git-send-email-repk@triplefau.lt>

```
When libcurl has been statically compiled with openssl support they both
need to be linked in everytime libcurl is used.

During configuration this can be detected by looking for Curl_ssl_init
function symbol in libcurl, which will only be present if libcurl has been
compiled statically built with openssl.

configure.ac checks for Curl_ssl_init function in libcurl and if such function
exists; it sets NEEDS_SSL_WITH_CURL that is used by the Makefile to include
-lssl alongside with -lcurl.
