net/appkonference: Schedule for removal on 2021-12-31

This port is outdated in several ways:
- port has version 2.8, while 2.9 is out
- relies on EOL net/asterisk13
- uses c89, fcommon, etc

Reported by:	Tomoaki AOKI <junchoon@dec.sakura.ne.jp>

net/appkonference: Mark as broken and unbreak index

net/asterisk13 is gone and it does not build with net/asterisk1{6,8}

Remove # $FreeBSD$ from Makefiles.

Allow building on powerpc64le.

net/appkonference: fix build on recent current

net/appkonference: fix build on powerpc64

net/appkonference: Update to 2.8

PR:		248079
Submitted by:	Marcel Bischoff <marcel@herrbischoff.com>

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Remove options to compile these ports against net/asterisk11 in
preparation for port expiration.

asterisk 11.x will EOL on 2017-10-25 and is scheduled for removal.

Please use the net/asterisk13 port.

For ports that are explicitly enabled on armv6, also enable them
on armv7.  This has not been tested with an -exp run but should
"do no harm".
