libgcc8 build failure (stage comparison) on Snow Leopard

[Riccardo Mottola]

Hi all,

I hope my cctools built with clang 3.4 is working fine :)

Next in the upgrade on 10.6.8 process is libgcc which is libgcc8 now 
(last time I built it it was still v7 IIRC) current outdated shows for me:

libgcc                         @1.0            lang/libgcc

The following ports are currently installed:
   libgcc @7.2.0_1+universal platform='darwin 10' archs='i386 x86_64' 
date='2017-11-20T23:16:37+0100'
   libgcc @7.3.0_0+universal platform='darwin 10' archs='i386 x86_64' 
date='2018-02-08T18:32:36+0100'
   libgcc @7.3.0_1+universal (active) platform='darwin 10' archs='i386 
x86_64' date='2018-06-04T13:09:34+0200'

Anyway, the build failure is a comparison failure of the stage. Never 
seen this issue building libgcc! Did you get it?
Since I build gcc as universal it is too.
