Yes seems so ...

Target CPU family is same: "arm", but Target processor is not the same: 
"ARMv4" versus "ARMv7" ...

So I do not know if this requires two pre-compiled cross-compilers or not?

I can set in Project Options "Unit Output Directory", but how to set 
where RTL/packages are located ...

Perphas recompilation RTL/packages for given target processor from 
sources is okay for me, but is it doable in one Lazarus with one cross
