I have been away for a couple of days, so I didn't yet have a chance to
do further tests.

I am on a custom imx6q-based board. We do full cross-compilation from an
x86-based Linux system. Our versions are quite old compared to yours:

Yes, I can recompile everything and run some commands you tell me to.

I had to convert the build process to the framework we use. Maybe
something went wrong there? Is there anything in particular that I need
to look out for? Also I don't do the 'make install', because I didn't
want to add asciidoc and xmlto dependencies on the host just for the
sake of the documentation.
