Subject: [PATCH 00/10] tools/nolibc: split out functionality into new
 headers

Porting applications to nolibc is made harder by the lack of standard
header names. Split out the existing functionality from the big catch-all
headers into new dedicated ones.

This series does not introduce any new logic.

The last patch for sys/wait.h will conflict with 
"tools/nolibc: implement waitpid() in terms of waitid()" [0].
But as both patches will go through the nolibc tree anyways we can take
care of the conflict there.

Based on linux-nolibc.git/next
