+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
+https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=682cc4e678aceff32dea2a84b6e5147bdf5a20a7:

+In file included from ./sys/random.h:40,

+/tmp/instance-0/output-1/per-package/tar/host/x86_64-buildroot-linux-uclibc/sysroot/usr/include/sys/random.h:27:35: error: unknown type name 'size_t'

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