I'll have to make a setup for that. Might take some days due other tasks.

It might be that I setup the jail tree to not use compat. But rather have
a complete linux system tree at jail root. Ie linux files in /bin/ not
/compat/linux/bin/

That way when software like Xilinx tries to modify/access /usr/X11R6 files it
get's the linux files it expect.
