 > One possibility is the issue is nothing to do with the gcc ports per se,
 but due to other changes made recently in ports like ld64 and cctools,
 which gcc uses. You are seeing this now simply because the new gcc ports
 are forcing you to rebuild with them.

 Exactly these changed recently:

 {{{
   cctools @895_5 (active) platform='darwin 8' archs='ppc'
 date='2018-08-04T21:30:39+0200'
   ld64 @3_1+ld64_97 (active) platform='darwin 8' archs='ppc'
 date='2018-08-04T21:06:51+0200'
   ld64-97 @97.17_8 (active) platform='darwin 8' archs='ppc'
 date='2016-12-22T21:53:15+0100'
 }}}

 Wouldn't it be advised to report this failure with `libgcc7` to the
 maintainer of `cctools` and `ld64`?
