Failure to cross compile GStreamer v1.14 with config/cross-lin-arm.cbc

Greetings gstreamer-devel list,

I'm wishing to build and package GStreamer v1.14 (or later) for the ARM32 hard-float architecture (for Raspberry Pi 2, 3, 3B+). I mean the GNU Triplet: arm-linux-gnueabihf. I'm doing this in an Ubuntu docker container in an up-to-date Ubuntu 16.04 LTS x86_64 VM to ensure a clean environment.
I see that "config/linux.config" doesn't actually support the hard-float ARMv7 variant but just to get familiar with the process I've decided to test the cross compilation using the "config/cross-lin-arm.cbc" configuration (which I believe will build for arm-linux-gnueabi).

The build fails during stage 62 of 78 which is the linking during the compilation of openssl-1.1.0h. The error messages of the failure are:
[(62/78) openssl -> compile ]
Running command 'make CC="$CC $CFLAGS" LDFLAG="$LDFLAGS -fPIC" CFLAG="$CFLAGS -fPIC -DOPENSSL_PIC"'

I have confirmed that a native compile (on a Raspberry Pi 3 running Ubuntu MATE 16.04 aarch32) does get past this stage and completes (but fails to package as I'll describe in another email).
Does anyone have a solution for this issue?
For completeness/reproducibility, my complete steps are:

  1.  docker run -it ubuntu
  2.  apt install -y sudo python3 python-dev git intltool
  3.  echo -e "[user]\n\tname = Matthew Thyer\n\temail = Matthew.Thyer at adelaide.edu.au" >~/.gitconfig
  4.  apt install -y g++-arm-linux-gnueabi
  5.  mkdir ~/git
  6.  cd ~/git
  7.  git clone git://anongit.freedesktop.org/gstreamer/cerbero
  8.  ./cerbero-uninstalled -c ~/git/cerbero/config/cross-lin-arm.cbc bootstrap
  9.  ./cerbero-uninstalled -c ~/git/cerbero/config/cross-lin-arm.cbc package gstreamer-1.0

Regards,
