go1.8-1.8.5-2.1

- Update to go1.8.5
  go1.8.5 (released 2017/10/25) includes fixes to the compiler,
  linker, runtime, documentation, go command, and the crypto/x509
  and net/smtp packages. It includes a fix to a bug introduced in
  Go 1.8.4 that broke go get of non-Git repositories under certain
  conditions. See the Go 1.8.5 milestone on our issue tracker for
  details.

- Install $GOROOT/lib packages, to include upstream files such as the timezone
  database. bsc#1064522

- Update to go1.8.4
  go1.8.4 (released 2017/10/04) includes two security fixes. It
  contains the same fixes as Go 1.9.1 and was released at the same
  time. See the Go 1.8.4 milestone on our issue tracker for
  details.
  Fixes included:
  * net/smtp: fix PlainAuth to refuse to send passwords to non-TLS
    servers (CVE-2017-15042, bsc#1062087)
  * cmd/go: arbitrary code execution during ?go get? or ?go get -d?
    (CVE-2017-15041, bsc#1062085)

- Rename to go1.8

- Fixed incorrectly ghosted files

- add fix-sanitizer-build-against-latest-glibc.patch which fixes
  the sanitizer built against certain glibc versions

- go-race: add compiler-rt TSAN binary, necessary for the race detector builds
  to work. This requires building compiler-rt from source (becuase upstream Go
  stores precompiled binaries in the tree, and we cannot use them). In
  addition, a %check was added purely to ensure that we don't install the wrong
  version of compiler-rt. boo#1052528
- go-rpmlintrc: add some entries to address the .syso additions.

- Remove ruby requirement. golang-macros are not ruby anymore, plus
  this requirement should have been in the golang-packaging package

- Simplify all the "ifdef suse_version" by removing versions which
  have reach eol (13.* 42.1 sle11*)

- Add gcc6-go.patch for sle12 and leap42.x and use binutils-gold
  except for s390x/s390
  Remove gcc5-go.patch cause we use gcc6 for sle12 and leap42.x and
  gcc7 for newer versions (factory)

- build with binutils-gold on aarch64, which is hardcoded to
  be used for shared linking due to bugs in BFD binutils

- Build with gcc-7 on Tumbleweed
  + Add gcc7-go.patch

- Minor update to go1.8.3
  Fixes included:
  * go1.8.2 (released 2017/05/23) includes a security fix to the
    crypto/elliptic package (CVE-2017-8932, bsc#1040618).
  * go1.8.3 (released 2017/05/24) includes fixes to the compiler, runtime,
    documentation, and the database/sql package.

- Enable gccgo with gcc-6 for SLE12

- fix update-alternatives usage. This way, we can either use go1.7 or
  go 1.8 without having to change the docker spec file or any other
  package that requires go 1.7 but it will require go 1.8 in the
  future.

- Update to go1.8.1
  Most of its changes are in the implementation of the toolchain, runtime, and
  libraries. There are two minor changes to the language specification. As
  always, the release maintains the Go 1 promise of compatibility. We expect
  almost all Go programs to continue to compile and run as before.
  The release adds support for 32-bit MIPS, updates the compiler back end to
  generate more efficient code, reduces GC pauses by eliminating stop-the-world
  stack rescanning, adds HTTP/2 Push support, adds HTTP graceful shutdown, adds
  more context support, enables profiling mutexes, and simplifies sorting
  slices.

  Update patches:
  - allow-binary-only-packages.patch
  - gcc5-go.patch
  - gcc6-go.patch

- Remove mercurial build dependency. Mercurial is a version control
  system, like git. We are not using this in the build service to
  get the sources.
- Do not set GOBIN. If GOBIN is unset, by default go assumes GOPATH/bin.
  This way, the user can change GOPATH without the need to change GOBIN.
  fix bsc#1026658

- Add a patch to bump _MaxGomaxprocs so that things like Docker and k8s can run
  properly on NUMA machines. Don't bump this number too high. bsc#1028865
  + runtime-bump-MaxGomaxprocs.patch

- set libdir for s390x in go.sh
