gentoo-overlay/dev-ruby/RubyInline/files/ruby-inline-3.12.2-gentoo.patch

we have to patch the code so that it takes the RUBY_DESCRIPTION into
consideration, to avoid loading Ruby-Enterprise (REE18) objects in MRI
and vice-versa; we're a bit “greedier” since we will rebuild objects
even when just switching versions, but it'll be better this way than
being too conservatives.
