Looking for something starting with '-Wl,-rpath,' isn't good enough, as someone might give something like '-Wl,--enable-new-dtags,-rpath,/PATH'. Looking for ',-rpath,' should be safe enough. We could remove the preloading stuff entirely, but just in case the user has chosen to given RPATH setting arguments at configuration, we'd better make sure testing will still work. Fair warning, there are some configuration options that do not work with preloaded OpenSSL libraries, such as the sanity checking ones. Reviewed-by: Rich Salz <rsalz@openssl.org>
