Yes, of course tis is possible. We use the ELDK for example to  build
the  U-Boot  boot  loader on a plethora of systems - which is nothing
else but a (bigger) standalone executable.

You will have to be careful about assumptions about:
- C runtime envrionment (there is none, or you have to set it up yourself)
- library usage (standard C libs require full C runtime envrionment
  plus some other things like standard file descriptors, etc.)

Feel free to have a look at U-Boot...

How did you set up your C runtim environment, for example: allocate a
stack, initialize the "parent" stack frame, etc. ?
