While bootstrapping the tilegx architecture for Debian, I noticed that
libatomic-ops lacks support for tilegx. Gladly, gcc-6 provides working
atomics, so the implementation on behalf of libatomic-ops is simple.
The issue is fixed properly in upstream git, see forwarded address
above. Updating to libatomic-ops 7.4.4 is insufficient. No released
version seems to ship the commit yet.
It can either be fixed by updating the package to git or by temporarily
applying the attached simplified patch. In the latter case, #821068 also
needs to be fixed, because the patch touches Makefile.am.
