Fix for GCC 10

Host machine: Ubuntu 18.04
Buildroot version: 2020.08.2
Target: i586-buildroot-linux-musl-gcc (GCC 10.2.0)

Trying to build OpenRC 0.42.1 fails when compiling with GCC 10.x. It evidently will also fail with prior major versions when the '-fno-common' flag is explicitly used (this flag seems to be the default now on GCC 10.x, hence the failure).

I've attached a patch I found from Gentoo that fixes this issue.
