* Since r1724820 two modules, mod_http2 and mod_ssl, call APACHE_CHECK_OPENSSL,

  with mod_http2 doing it first. Because the result of APACHE_CHECK_OPENSSL
  is cached this causes MOD_LDFLAGS and MOD_CFLAGS to remain unset for mod_ssl
  which in turn causes it not to be linked against Openssl which means that
  mod_ssl cannot be loaded if the Openssl libs haven't been loaded by other means
  already.
  Fix this by caching the values for MOD_LDFLAGS and MOD_CFLAGS created during
  the first run and set them in the cached case.
