### Implementation from Platform

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 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).
