Compiling latest aircrack-ng failed on ARM 32bit

[Ralf Wenk]

Hello,

the maintainer (Lars Engels) of the aircrack-ng port directed me to this
(ports at freebsd.org) list.

When trying to upgrade the aircrack-ng port the configure script ran
into the following error:

  configure: error: _AX_COMPILER_VERSION_GNU unknown gcc major


The system I try to upgrade aircrack-ng is an RaspberryPI B.
Kernel and world are cross-compiled and relatively new
# uname -a                                                                     

FreeBSD IZ-WLAN 12.0-CURRENT FreeBSD 12.0-CURRENT #2 r336070M:\
 Sat Jul  7 21:46:46 CEST 2018\
     root at hs-karlsruhe.de:/usr/obj/usr/src/arm.armv6/sys/RPI-Bsc  arm
# 

The latest known working version on that system is aircrack-ng-1.2.r4_1.
Both newer versions from ports failed with the same error message.


The configure script stops with:

...
checking whether C compiler accepts -Wno-unused-but-set-variable... yes
checking whether C compiler accepts -Wno-array-bounds... yes
checking for C++ compiler vendor... gnu
checking for C++ compiler version... configure: error: in

See `config.log' for more details
===>  Script "configure" failed unexpectedly.
Please report the problem to ports at FreeBSD.org [maintainer] and attach the
"/usr/ports/net-mgmt/aircrack-ng/work/aircrack-ng-1.3/config.log" including
the output of the failure of your make command. Also, it might be a good idea
to provide an overview of all packages installed on your system (e.g. a
/usr/local/sbin/pkg-static info -g -Ea).

In total config.log contains 4592 lines, so I do not include it whole.
Related to the error message it contains after two thirds of the lines:
