Starting from the upcoming GCC release 10, the default of -fcommon option will change to -fno-common:

In C, global variables with multiple tentative definitions will result in linker errors. Global variable accesses are also more efficient on various targets.

The latest cpio fails to build with -fno-common option. I'm attaching a build log.

Thanks for fixing it.

Best regards,
