This is a general  problem for generating cross configurations...

I want to:
	do linux/go32 on linux
	do sparc/lynx-sparc/linux/go32 on sun/sparc


I made binutils on linux for linux and go32...
(its working for 2.5.1). 

Since I understand you need a different assembler
for each target:
	1) I made the binutils and ld for go32 and linux
	2) I made an assembler for linux
	3) I made an assembler for go32

I have a trivial C program:
main() {
 printf("Hello world\n");
}

Both produce the following assembler:
       .file   "hello.c"
gcc2_compiled.:
___gnu_compiled_c:
.text
LC0:
        .ascii "Hello world\12\0"
        .align 4
.globl _main
_main:
        pushl %ebp
        movl %esp,%ebp
        call ___main
        pushl $LC0
        call _printf
        addl $4,%esp
L1:
        movl %ebp,%esp
        popl %ebp
        ret

When I use the go32 version nm I get:
marty AT compaq$ nm hello.o
0000002c b .bss
0000002c d .data
00000000 t .text
00000025 t L1
00000000 t LC0
00000000 t ___gnu_compiled_c
         U ___main
00000010 T _main
         U _printf
00000000 t gcc2_compiled.

hello.o is 521 bytes...

For linux:
marty AT compaq$ nm hello.o
00000000 t ___gnu_compiled_c
         U ___main
00000010 T _main
         U _printf
00000000 t gcc2_compiled.
marty AT compaq$ ls -l hello.o
- - -rw-r--r--   1 marty    users         219 Oct 31 23:27 hello.o

I'm not sure whatis different --
on Linux it knows enough that I'm not interested in the .text, .bss, etc...
and the internal jumps...but its present in go32...

How can I get the assembler and nm  to eat the  internal jumps and .text, .data, .bss symbols?
