We use two patches to alter the specs file depending on which version of 
the book you use, these basically tell gcc to look in certain 
directories for the startup files and which linker to use, if you are 
changing the the library directory on the command line to something 
different, it's going to get horribly confused.

if you want to alter the layout you will have to change the patch, so it 
matches your own layout
