How to using 'LD' to align on my AMD64?

[bsdmaillist]

Hello,

On my AMD64 machine, I'd like to link my object file to a image,
the image is flat, code is from 0x0000, and contains debug symbol.

I wrote a ld script file, but the output file is over 1MB !!
(I guess because the align is 0x0100000, so the ELF header is from 0x0,
 the next program: .text is on 0x0100000)

So how to modify the ld script file?
Thanks in advance!!

This is my ld script file:

SECTIONS
{
. = 0x000000;

.text : { *(.text) }

. = ADDR(.text)+SIZEOF(.text);

.data : {*(.data)}

.rodata : {*(.rodata)}

.bss : {*(.bss)}

.eh_frame : {*(.eh_frame)}

 _edata = ADDR(.bss)+SIZEOF(.bss)+0x04000;

}
