net/openbgpd6: update 6.6.0 -> 6.8.0, fix -fno-common

6.8.0:
- In bgpctl(8), the "reload" command now takes a 'reason' argument
  to use as Administrative Shutdown Communication to its neighbors.
- Added bgpctl(8) support for VPNv6 in the family option of the
  "show rib" command.
- Added bgpctl(8) support for JSON formatted output in various
  "show" commands.
- Support to build OpenBGPD on Alpine Linux added

6.7.0:
- Add initial support for JSON output in bgpctl(8).
- Allow setting both IPv4 and IPv6 local-addresses at the same
  time in bgpd.conf group blocks.  Introduced 'no local-address'
  to reset a previously set local address.
- Properly aggregate duplicate bgpd(8) roa table prefix/source-as
  combinations into a single entry with the longest maxlen length.
- Implemented bgpd.conf(5) max-prefix NUM out to limit the number
  of announced prefixes, avoiding leaks of full tables to upstreams
  and peers.
- Extended bgpctl(8) 'show neighbor' to include the received and set
  prefix count, as well as the max-prefix out limit if set.
- Improved reporting of notifications to include the suberror cause.
- Also report the last received error cause in bgpctl(8) show neighbor
  output.
- Fix softreconfig out handling to also work for neighbors using
  'export default-route'.
- Mark stale prefixes in the Adj-RIB-Out so that graceful reload
  operates properly.
- Made it possible to build OpenBGPD-portable with bison. There is
  no longer the need to use byacc on Linux distributions.
- Support for --runstatedir to specify the location of the bgpctl.sock.
- Cleaned up configure script for better protability.
