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. Signed-off-by: Waldemar Brodkorb <wbx@uclibc-ng.org>

+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.
