updated iphone build script.

[shayne.oneill@xxxxxxxxx (Shayne O'Neill)]

This cross compiles to both simulator AND phone. In general follow the  
siphon instructions, but pay attention to the need for i386-xxx  
compiler linkeages. There are i686-xxxx linkeages in the SDK which  
will need to be simlinked.

This is an adaption of a generic "Compile autoconf for iphone" script  
I've found very useful

use simulator or device as a parameter
