BusyBox has been doing this for months now: "build at once" is one of our config options. I'd like to point out that gcc eats needs several hundred megabytes of ram to do this and you have no useful progress indicator between starting and ending. But the result is definitely smaller.
We also tell the linker "--sort-common --gc-sections" which may or may not apply here...
