For AVR, I use following commands:
$ make
ADA_PROJECT_PATH=/usr/local/avr/ada avr-gnatmake -XMCU=atmega328p -Phello.gpr --RTS=rts/atmega328p
avr-gcc -c -gnatec=/usr/local/avr/ada/gnat.adc -gdwarf-2 -gnatwp -gnatwu -gnatn -gnatp -gnatVn -Os -gnatef -fverbose-asm -frename-registers -mmcu=atmega328p -gnateDMCU=atmega328p -fdata-sections -ffunction-sections --RTS=rts/atmega328p -I- -gnatA /home/tkoskine/work/arduino/hello/hello.adb
avr-gnatbind -freestanding --RTS=rts/atmega328p -I- -x /home/tkoskine/work/arduino/hello/objects/hello.ali
avr-gnatlink /home/tkoskine/work/arduino/hello/objects/hello.ali -Wl,--gc-sections -gdwarf-2 -Wl,--relax --GCC=avr-gcc -Os -mmcu=atmega328p --RTS=rts/atmega328p -fdata-sections -ffunction-sections -Wl,-Map=../hello.map,--cref -L/usr/local/avr/ada/avr_lib/atmega328p/lib -lavrada -o /home/tkoskine/work/arduino/hello/hello.elf
avr-objcopy -O ihex -R .eeprom hello.elf hello.hex
$
Resulting file is something like:
$ cat hello.hex

This was for AVR/AVR-Ada, but I think the idea
applies to raw i386 programs also. By changing
the target of -O parameter, you can probably get
the output you want.
