Bug #21521: Don't require dummy makefile in `extconf.rb`

On some platforms, no native extensions should be created. Due to limitations in mkmf, it is typical to create a dummy makefile that does nothing:

https://github.com/search?q=File.write+Makefile+path%3A**%2Fextconf.rb&type=code

This seems like a bad pattern, I think it would be preferable to just do:

# extconf.rb

return if build_not_required?

require "mkmf"

...

create_makefile

Actually, this is probably a bug with RubyGems.
