Waldemar Brodkorb 5d8ece87a4 util-linux: fix scanf fallback detection for uClibc-ng
uClibc-ng pretends to be GNU libc 2.2 and then a fallback
scanf check is tried, so that libmount is disabled
afterwards. Add a fix already suggested upstream.
Add librt dependency required for other apps, too.

Subject: [PATCH] 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.
