Closed for now. This is now documented as KNOWN_BUG #83. Hopefully someone in possession of external openssl engines can help us work on this in the future.

curl is unable to load non-default openssl engines, because openssl isn't initialized properly - curl ignores the openssl configutration file. for example curl cannot load ccgost engine, provided since 1.0.0:
    # /usr/local/openssl/bin/openssl engine
    (rsax) RSAX engine support
    (rdrand) Intel RDRAND engine
    (dynamic) Dynamic engine loading support
    (gost) Reference implementation of GOST engine
    # ldd /usr/local/curl/bin/curl
        linux-vdso.so.1 =>  (0x00007fff0c9ff000)
        libcurl.so.4 => /usr/local/curl/lib/libcurl.so.4 (0x00007fb5f1f17000)
        libz.so.1 => /usr/lib/libz.so.1 (0x00007fb5f1d00000)
        librt.so.1 => /lib/librt.so.1 (0x00007fb5f1af7000)
        libc.so.6 => /lib/libc.so.6 (0x00007fb5f1795000)
        libssl.so.1.0.0 => /usr/local/openssl/lib/libssl.so.1.0.0 (0x00007fb5f152c000)
        libcrypto.so.1.0.0 => /usr/local/openssl/lib/libcrypto.so.1.0.0 (0x00007fb5f1151000)
        libpthread.so.0 => /lib/libpthread.so.0 (0x00007fb5f0f35000)
        /lib64/ld-linux-x86-64.so.2 (0x00007fb5f2178000)
        libdl.so.2 => /lib/libdl.so.2 (0x00007fb5f0d31000)
    # /usr/local/curl/bin//curl --engine list
    Build-time engines:
      rsax
      rdrand
      dynamic
"It is strongly recommended that all new applications call OPENSSL_config() or the more sophisticated functions such as CONF_modules_load() during initialization (that is before starting any threads). By doing this an application does not need to keep track of all configuration options and some new functionality can be supported automatically." - curl totally ignores this openssl note.
The patch provided fixes the issue.
