Workaround build failure on -fno-common toolchains like upstream
gcc-10. Otherwise build fails as:
ld: lockdep.o:/build/linux-5.0.21/tools/lib/lockdep/../../include/linux/rcu.h:5: multiple definition of
`rcu_scheduler_active'; common.o:/build/linux-5.0.21/tools/lib/lockdep/../../include/linux/rcu.h:5: first defined here
