Get SSL support working on OpenSolaris.  Unfortunately on OpenSolairs the
OpenSSL install is split between /lib and /usr/include/openssl with plays
havoc with the php ./configure as it assumes both have the same base
directory (e.g. /usr).  This patch uses a modified inbuilt check for
OpenSSL instead of explicitly specifying a base using --with-openssl.
