ruby-build 20210510

* Join *_OPTS variables after *_OPTS_ARRAY variables

  This for instance allows `RUBY_CONFIGURE_OPTS` to override
  what's set by the definition.

  For instance `enable_shared` can be disabled with `RUBY_CONFIGURE_OPTS='--disable-shared'`

* Do not append `--enable-shared` if RUBY_CONFIGURE_OPTS include `--disable-shared`
