Does .head.text actually need its own output section here?  I notice that 
only the linker scripts for arm, x86, and ia64 have an output section for 
.head.text; the rest just place it at the start of the .text or .init.text 
output section.  It would be great if we could eliminate these extra 
references to .head.text by doing the same thing here.
