Tried adding -fPIE to CMAKE_CXX_FLAGS (not sure if that's where it belongs) as per the message's suggestion, didn't work.

Thanks for this. Setting the relocation model to PIC when constructing the target machine appears to have fixed the problem (tested using the manjarolinux/base Docker container).

That solved it, thanks!
