TruffleRuby >= 24 defines REUSE_AS_BINARY_ON_TRUFFLERUBY in defaults/truffleruby. However, TruffleRuby < 24 defines REUSE_AS_BINARY_ON_TRUFFLERUBY directly in its copy of lib/rubygems/platform.rb, so it is not defined if RubyGems is updated (gem update –system). Instead, we define it here in that case, similar to bundler/lib/bundler/rubygems_ext.rb. We must define it here and not in platform.rb because platform.rb is loaded before defaults/truffleruby.
Available list of platforms for targeting Gem installations.
See ‘gem help platform` for information on platform matching.
A pure-Ruby gem that may use Gem::Specification#extensions to build binary files.
A platform-specific gem that is built for the packaging Ruby’s platform. This will be replaced with Gem::Platform::local.

end
Does other match this platform? Two platforms match if they have the same CPU, or either has a CPU of ‘universal’, they have the same OS, and they have the same version, or either one has no version
Additionally, the platform will match if the local CPU is ‘arm’ and the other CPU starts with “armv” (for generic 32-bit ARM family support).
Of note, this method is not commutative. Indeed the OS ‘linux’ has a special case: the version is the libc name, yet while “no version” stands as a wildcard for a binary gem platform (as for other OSes), for the runtime platform “no version” stands for ‘gnu’. To be able to distinguish these, the method receiver is the gem platform, while the argument is the runtime platform.
