commit: http://git.buildroot.net/buildroot/commit/?id=52717eac86da18d4de08220d2c59d29086cf147f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

The bump to uClibc-ng 1.0.8 added some changes in <unistd.h> related
to syncfs() that broke the build for packages including this header
file, such as lighttpd. This commit adds a uClibc-ng patch (submitted
upstream) which fixes the issue.

+Commit dfa593d4d881116723a4401b466ea964fb12327b ("syncfs: add system
+call support") modified the #if condition around the definition of the
+syncfs() prototype in a way that doesn't build, causing build failures
+of any file including <unistd.h>:
