   4 Subject: [PATCH] build-sys: fix uClibc-ng scanf check
   5
   6 uClibc-ng tries to be compatible with GNU libc and defines
   7 __GLIBC__ and pretend to be version 2.2.
   8 We once changed it to 2.10, but then some hard to fix problems
   9 in different software packages (gcc) occured.
  10 It would be better if we disable the special GNU libc checks
  11 for uClibc-ng here. uClibc-ng implements the required scanf
  12 functionality.
