Do we think the __need_* interface is a good idea?

[Carlos O'Donell]

Joseph,

In the upstream kernel their signal.h has exactly the same
issues that ours does, for example they need a definition of size_t:

I mention here how we solve this:
https://lkml.org/lkml/2017/3/2/364

Is our use of special "hooks" like __need_size_t something we want
to keep using or has someone thought of a better solution?
