+Subject: [PATCH] criu: fix build failure against gcc-10
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+On gcc-10 (and gcc-9 -fno-common) build fails as:
+
+```
+ld: criu/arch/x86/crtools.o:criu/include/cr_options.h:159:
+ multiple definition of `rpc_cfg_file'; criu/arch/x86/cpu.o:criu/include/cr_options.h:159: first defined here
+make[2]: *** [scripts/nmk/scripts/build.mk:164: criu/arch/x86/crtools.built-in.o] Error 1
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+https://gcc.gnu.org/PR85678.
+
+The error also happens if CFLAGS=-fno-common passed explicitly.
