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
.

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 “arm” (for generic 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 disinguish these, the method receiver is the gem platform, while the argument is the runtime platform.
