libgcc8 build failure (stage comparison) on Snow Leopard

[Chris Jones]

Hi,

libgcc8 builds just fine on 10.6 with its default variants. Its 
difficult to say if your issue is due to your use of the universal 
variant (do you *really* need to build everything with this ??) or 
something else on your system.

Note, your error is quite similar to that in

https://trac.macports.org/ticket/56922

Please post information there, if you think its possibly related, or 
start a new ticket. its much easier to track that way than via emails. 
When you do remember to post *complete* log files from clean builds, not 
just snippets.

cheers Chris
