+Subject: [PATCH] lib/getrandom.c: fix build with uclibc < 1.0.35

+Fix the following build failure with uclibc < 1.0.35 which is raised
+since the addition of getrandom module in

+This patch is not upstreamable as it is only a workaround for
+uclibc < 1.0.35, upstream uclibc has been patched with
