curl rebuild

configure:29155: checking for curl_easy_perform in -lcurl
configure:29180: ccache gcc -o conftest -O2 -fwrapv -pipe -Wformat -Werror=format-security -gdwarf-4 -fno-debug-types-section -fvar-tracking-assignments -g2 -Wp,-D_FORTIFY_SOURCE=2
/usr/lib/gcc/i686-pld-linux/5.3.0/../../../libcurl.so: undefined reference to `SSLv2_client_method'
collect2: error: ld returned 1 exit status

altho this dependency is compile time, it's easier to mark it here than
all rebuilt programs that link with curl (php55-openssl, php56-openssl, ...)
