go1.11-1.11.13-bp153.2.72

- Ensure ARM arch is set properly - boo#1169832

- Requires binutils-gold for %arm and aarch64 - boo#1170826

- armv7 build hangs with gcc7-go on Leap 15.2, so use go1.4 (bsc#1167874)

- %arm requires binutils-gold to build with go1.4 (bsc#1167874)

- Make use of gcc9-go for Tumbleweed since gcc8 has been dropped
- Drop gcc8-go.patch and add gcc9-go.patch

- Fix broken go_api evaluation (1.11 < 1.5, when evaluated as floats),
  let RPM evaluate the expression, drop no longer required bc.
- Own the gdbinit.d directory, avoid the build dependency on gdb.

- go1.11.13 (released 2019/08/13) includes security fixes to the

  * bnc#1146115 VUL-0: CVE-2019-9514: go: HTTP/2 implementation is vulnerable to a reset flood, potentially leading to a denial of service
  * bnc#1146123 VUL-0: CVE-2019-14809: go: malformed hosts in URLs leads to authorization bypass
  * go#33632 net/url: URL.Parse Multiple Parsing Issues
  * go#33630 net/http: Denial of Service vulnerabilities in the HTTP/2 implementation

- go1.11.12 (released 2019/07/08) includes fixes to the compiler and
  the linker.
  Refs boo#1141688.
  * go#32711 cmd/compile: wrong calculation result for bit operation
    that's inlined and has all constant shifts in rewrite rules
  * go#32696 debug/dwarf: cgo produces malformed DWARF data
  * go#32582 cmd/compile: `switch` statement on a custom `int32` type
    with negative values behaves differently in two consecutive calls

- Set NO_BRP_AR in order to workaround issues when ar is used for
  a Go ELF file.

- BuildRequire pkgconfig(systemd) instead of systemd: allow OBS to
  shortcut the build queues by allowing usage of systemd-mini.
