Include Ard who made this change to discard COMMON section (edk2 214a3b79417f64bf2faae74af42c1b9d23f50dc8).
Ard: can you help confirm this change to add back COMMON section?
Christopher adds back COMMON section for GCC support from the assembly-accelerated OpenSSL patch.
Because -fno-common option is still kept, COMMON section can be added.
Thanks
