I confirm that this is the case. The following backtrace is produced when
cross-building and installing Android x86_64 on a linux x86_64:
PYTHONPATH=/sdcard/org.bitbucket.pyona/lib/python3.6 \
_PYTHON_PROJECT_BASE=/home/xavier/src/android/pyona/build/python3.6-android-21-x86_64
_PYTHON_HOST_PLATFORM=linux-x86_64
PYTHONPATH=/home/xavier/src/android/pyona/build/python3.6-android-21-x86_64/build/lib.linux-x86_64-3.6:/home/xavier/src/packages/android/cpython/Lib:/home/xavier/src/packages/android/cpython/Lib/plat-x86_64-linux-gnu
python3.6 -Wi /sdcard/org.bitbucket.pyona/lib/python3.6/compileall.py \
-d /sdcard/org.bitbucket.pyona/lib/python3.6 -f \
-x 'bad_coding|badsyntax|site-packages|lib2to3/tests/data' \

'python3.6' is the native interpreter built from the same source tree as the
source tree used for the cross-build. PATH has been set so that this native
interpreter is run. Running this same command interactively with the native
interpreter gives the same result:
[xavier@bilboquet python-native]$

Cross-building and installing Android i686 on a linux x86_64 with the same
Makefile does not cause the problem.
Adding -E to PYTHON_FOR_BUILD fixes the x86_64 install.
