Did you install the binutils?
Did you crossbuild the linux fpc files?

fpc calls for example ppcx64, which can cross compile to other OS for
all x86_64 targets. But you need the cross compiled ppu and o
files for this target, here linux. And for Linux you need the binutils
as well. See the wiki.

That only works after installing the cross compiled fpc files.
After changing the target OS, when you click Ok of the Project
Options, you should have seen an Error dialog "Compiler
C:\lazarus\....exe does not support target x86_64-linux".
