> The COMMON section is used by OpenSSL assembly-optimized crypto
> functions. OpenSSL assembly code is auto-generated from the submodule
> and cannot be modified to remove dependence on the COMMON section.
> The default -fno-common compiler flag should still prevent variable from
> being emitted into the COMMON section.
