[darwinbuild] Size of mach_kernel when using darwinbuild?

[Shantonu Sen]

You missed a decimal. The symbols version is 51MB, which is correct.  
the Roots/ version is 7.8MB, which is also correct, for a fat (ppc 
+i386) kernel.

Because there's code for both PowerPC and Intel, it's about twice as  
large as the version on your running system in /
