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.
