Documentation needed: Purpose of nativeBuildInputs

[Profpatsch]

It is not at all clear to me what the difference to buildInputs is.

See also #1915

stuff like flex/bison/pkg-config/cmake should hit there. But also it does matter only on crosscompiling, when buildInputs resolved as target arch, and nativeBuildInputs is build arch.

btw would be nice if you retitle issue about fix documentation to be more clear

Let's extend #1915 not to have two issues for the same thing :)

That’s why I linked #1915.
This issue is explicitly about providing an explanation until someone gets his ass up and finally documents it (which should have happened once it was introduced).
