It is there.
I just showed the whole sequence to fully document, so you can see what's going
on.
The /usr/local/fpc-2.6.4/bin/fpc  with -sh flag generates a link script
(ppas.sh) and link.res and myprog.o

The ppas.sh you see there (and in the zipfile) invokes the linker as:
/usr/bin/ld -b elf64-x86-64 -m elf_x86_64     -Map myprog.map -L. -o myprog
link.res

The link.res has 3 files in the INPUT section:
  myprog.o
  and the 2 system files (prt0.o system.o), which I gave with the complete
subpath, and you can see in the zipfile.

All these files are in the attached zipfile. 
This should be the complete reproducible package needed, from what I can tell.  
I can't see any other files referenced.  If there are, let me know.

Just don't run 'make clean' or 'make dist' again.  
Start with ppas.sh
