Allow configuring the ruby-build options in a specific file (or asdfrc)

I need to build ruby with specific `RUBY_CONFIGURE_OPTS`. This works as expected, however I'd like to make it more persistent, so I don't have to set this variable every time I call `asdf install ruby`.

I know these could be added to my profile, but there are also options like `CC` and `MAKE` which would affect other build systems.

Unless I'm missing an existing solution here, could those options be imported from asdfrc before `ruby-build` is called?
