Instead of picking up /usr/include/asm/types.h (which in turn picks up 
/usr/include/asm-generic/types.h which picks up 
/usr/include/asm-generic/int-ll64.h), it is using 
openbios-devel/obj-sparc32/target/include/asm/types.h

This is because of the -I../target/include.

Not sure if this was the intent. I have a machine at work where this 
compile works, so I'll check to see what that machine is doing.
