On a related note, I see tons of the following warnings cross-building for
MIPS:

WARNING: init/mounts.o (.mdebug.abi32): unexpected non-allocatable section.
Did you forget to use "ax"/"aw" in a .S file?                              
Note that for example <linux/init.h> contains                              
section definitions for use in .S files.                                   

WARNING: init/mounts.o (.pdr): unexpected non-allocatable section.
Did you forget to use "ax"/"aw" in a .S file?                     
Note that for example <linux/init.h> contains                     
section definitions for use in .S files. 

I added ".pdr" and ".mdebug*" to the whitelist;  the resulting kernels still
work.  (gcc-4.3.3, binutils-2.19.1)

Thanks!
