Yes, You have right
I download mentioned toolchain and try to compile  simple program
as i notice libdl.so exists, but in other path ( its /sys-root/usr/lib)

I combine several directives and at last linker pass through  first phase

no others Xr, k,
I also not modify $PATH

By the way:
when XR path is set then XP should be default, but its not
FPC search arm-linux-as
maybe better search also "as" in <XR path>/bin/as
