I think you missed the point.  Can dietlibc act as a shared lib?  
Can dietlibc compile busybox and other real applications?
Sure, I can do static libs too (though it looks like I have 4 bytes
more overhead for the same trivial application -- I had to add in a
few useless things to make the shared lib loader happy).

    #include<stdio.h>
    #include <stdlib.h>

    int main(void)
    {
	printf("hello world\n");
	exit(42);
    }
