From bac7fbdb2d141879526ca4342d56d2c749ba8af5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] build-sys: fix uClibc-ng scanf check
uClibc-ng tries to be compatible with GNU libc and defines
__GLIBC__ and pretend to be version 2.2.
We once changed it to 2.10, but then some hard to fix problems
in different software packages (gcc) occured.
It would be better if we disable the special GNU libc checks
for uClibc-ng here. uClibc-ng implements the required scanf
functionality.
