svn commit: r494921 - head/lang/gcc8

[Gerald Pfeifer]

Author: gerald
Date: Thu Mar  7 09:55:52 2019
New Revision: 494921
URL: https://svnweb.freebsd.org/changeset/ports/494921

Log:
  No longer require a not too old version of GCC to build on powerpc64, but
  rely on the system compiler (even if that means we need to be explicitly
  conservative when it comes to optimizations). [1]
  
  Simplify the creation of the multilib-related sub-directory tree on
  powerpc64 and avoid leaving an empty directory behind on the way. [2]
  
  Sync pkg-descr with lang/gcc7-devel, in particular after r442530 there.
