Hi,

Please help review this quick patch in order to resolve the libj2gss link errors caused by GCC10 default option -fno-common. More details, please see JDK-8238388 and its related JDK-8235903 [1].

Weijun, I saw your comments in the ticket, thanks. It is exactly the same way I am updating the code. In addition, could you please sponsor this patch (once approved)? Thanks.
