For users not familiar with the ARM arch, neon is arguably more likely to
be associated with net-libs/neon. Certainly that's what I would have
immediately thought, tho my only familiarity with the library is as a
dependency that IIRC used to trigger lots of subversion rebuilds, etc
(now days I don't even have subversion on the system, it's all git, but
according to equery d, neon is still required by musicbrainz).
As such, to avoid confusion I'd suggest arch-neon or arm-neon (or armneon/
archneon) if it's to be a global flag.
