Author: andreast (src committer) Date: Thu Feb 16 18:38:27 2017 New Revision: 434238 URL: https://svnweb.freebsd.org/changeset/ports/434238 Log: Backport the bits needed for aarch64-*-freebsd* support from the gcc6-devel port. The same applies here as on the lang/gcc5 port, as soon as GCC releases a new gcc6, these bits go away. Iow, they are already part of the gcc6-devel branch.
