For some tests i finally succeeded to compile WSJT-X 1.7.0-devel with JTSDK.
https://sourceforge.net/projects/jtsdk/files/linux/
The documentation seems to differ from what needs to be done slightly. The difference was that i needed to place the jtsdk-xxx directory in my home directory and rename it to jtsdk. I used jtsdk to generate a .deb package. Find it below. Maybe its useful for someone.
I run a small Odroid U3 board with the Ubuntu 14.04.2 image from hardkernel. The board itself is obsolete meanwhile. Maybe the package can run on other ARM boards too.

I am not sure what dependencies you need. Please refer to the JTSDK readme if you need some guidance.

This is a screenshot of the software. I did not do a qso yet. So i cannot guarantee that it is really working well.
