where does OpenWrt claims, that it's fully POSIX compliant? Some deviations
are expected from the standards in exchange for lower flash usage. Maybe it
could be considered as `default y if !SMALL_FLASH` for devices with more flash
space, but then we would probably get inconsistent behaviour across various
targets and scripts wouldn't use this classes anyway.

So I don't see anything in favor for this patch inclusion.
