It should work. I use the GNU linker "ld". The LLVM linker 
"llvm-ld" should also accept the argument but I haven't tested 
it. I use the GNU linker because the LLVM linker is a bit 
immature for my purpose.

That is the size of the .elf files for the executable in my 
custom system, so application + druntime/phobos. All the 
debugging information was stripped. It is not an exact match of 
code+data but close enough to give you a rough idea of the size.
