how to reduce executable compiled file

[Rhenzo Losso]

I just made this test some right now on BSP SIS.

sparc-rtems-strip -s executable_name.exe -o strip-executable_name.exe

It was reduced a lot. from #MB to 140kB. After this I turn into binary.

sparc-rtems-objcopy -O binary strip-executable_name.exe
final-binary-name.bin
