[OpenBIOS] building openbios-qemu.elf?

[Hollis Blanchard]

Hi, I just tried to build openbios-qemu.elf, but it is a little too big
(1MB + 4 bytes):

Elf file type is EXEC (Executable file)
Entry point 0xfff08000
There are 3 program headers, starting at offset 52

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x000094 0xfff00000 0xfff00000 0x100000 0x100000 RWE 0x4
  LOAD           0x100094 0xfffffffc 0xfffffffc 0x00004 0x00004 R E 0x1
  GNU_STACK      0x000000 0x00000000 0x00000000 0x00000 0x00000 RWE 0x4

 Section to Segment mapping:
  Segment Sections...
   00     .text.vectors .text .rodata .data .sdata .bss .sbss 
   01     .romentry 
   02     

In contrast, the openbios-ppc binary in qemu looks like this:

Elf file type is EXEC (Executable file)
Entry point 0xfff08000
There are 2 program headers, starting at offset 52

Program Headers:
  Type           Offset   VirtAddr   PhysAddr   FileSiz MemSiz  Flg Align
  LOAD           0x000074 0xfff00000 0xfff00000 0x41044 0x4bc44 RWE 0x4
  LOAD           0x0410b8 0xfffffffc 0xfffffffc 0x00004 0x00004 R E 0x1

 Section to Segment mapping:
  Segment Sections...
   00     .text.vectors .text .rodata .data .sdata .bss .sbss.1 .sbss.2 .sbss.3 .sbss.4 .sbss.5 .sbss.6 .sbss.7 .sbss.8 
   01     .romentry 

I'm building with gcc 4.2.3. Any ideas?
