I am missing -FD/usr/bin/
The rest looks pretty ok to me.
Since it is a cross-compiler I seem to remember somehow that /usr/bin is not a default perse.
So give that a try.

The other option is that you point to real 32bit linker and assembler( instead of 64bit compiled versions that link and assemble 32 bit) , which will ONLY work on a dual 32/64 system, which you need to install.
That's called multiarch. You also have to install binutils-multiarch.

Thank you Thaddy  :)
I have found the solution , There is a difference between
 this
http://rpdev.net/home/book/export/html/33
and this
http://wiki.freepascal.org/Cross_compiling




The information in the fpc.wiki. Wrong


..the correct



/usr/bin/i386-linux-ld
Code: Pascal  [Select]
  1. #!/bin/bash
  2. ld -melf_i386 "$@"
  3.  
/usr/bin/i386-linux-as
Code: Pascal  [Select]
  1. #!/bin/bash
  2. as --32 "$@"
  3.
