We don't generally require that native sstate is rebuilt when the build
directory changes, as otherwise you wouldn't be able to share native sstate
between builds and users.  Instead, paths are munged where possible when
using sstate and wrapper scripts used to "fix" binaries.  Indeed
openssl.inc does this:

do_install_append_virtclass-native() {
        create_wrapper ${D}${bindir}/openssl \
            OPENSSL_CONF=${libdir}/ssl/openssl.cnf \
            SSL_CERT_DIR=${libdir}/ssl/certs \
            SSL_CERT_FILE=${libdir}/ssl/cert.pem \
            OPENSSL_ENGINES=${libdir}/ssl/engines
}

Is it possible that the binary isn't respecting the OPENSSL_CONF
environment variable since that wrapper was written? (or the wrapper wasn't
tested well enough)
