Unexpected (or unnecessary) dependency (once_cell) because of target_os incorrect usage #281
Description
Lines 89 to 90 in 4b73276
FYI target_os can be any random name, including name of some custom or rare OS.
And there is should no automated decision "to take once_cell with alloc or not to take" depending on target_os (or specifically on target_os=none) - this is the error.
I'm sure this should be a feature, but definitely not a relation to target_os or target_env.
As a hot-fix I could propose to use target-family (src-doc) instead, because it's more generic and can be array-of-values defined in the target.

I would say one should not use
not(target_os)for this purpose.Using dependencies FOR specific OS sounds alright.
So I propose replacing negative condition with explicit list of target_os or target_family.
