There should be something similar as C applications AFAIK rely on this. 
Otherwise we'd need to change arm-linux to use an internal sysinit like 
i386-linux and the Windows targets do.

I have taken a look at the compiler's code that leads to the inclusion 
of "crtn.o" (for the curious: 
compiler/systems/t_linux.pas/tlinkerlinux.WriteResponseFile). It 
searches for the file in the set library search path (this is extended 
by the "-Fl" option). Thus you should add - as Jonas wrote - the "-Xd" 
option which tells the compiler to not search in the default paths (the 
help of FPC even mentions that this option is "needed for cross 
compilation").
