[PATCH v2 0/2] nolibc: remove reliance on system headers

[Thomas Weißschuh]

This was prompted by the discussion about output directory support with
O=.
It seems sometimes we were pulling in system headers making testing
annoying and unreliable.

Willy:

I did not implement the '#ifdef va_start` guard that we discussed
before. In my understanding the latest agreement does not need it
anymore. Please let me know if this is incorrect.
