+Subject: [PATCH] libfrog: Fix cross-compilation issue with randbytes
+
+randbytes.c was mostly split off from crc32.c and, like crc32.c, is
+used for selftests, which are run on the build host. As such it should
+not include platform_defs.h which in turn includes urcu.h from
+userspace-rcu library, because the build host might not have the
+library installed.
