If we do keep one, it should probably be .hash -- see commit b02bfc4dfc.

I admit I'm completely mystified as to why we need the hash tables at 
all. The ELF spec says those are just for the dynamic linker, but 
neither the EFI code nor the self-relocating thunk require it, and I 
don't know of any target where the u-boot ELF itself is the shipped 
binary. For all I know, there never was a need to include .hash and 
Albert's commit fixed whatever problem he was facing only accidentally. 
Do you have any insights?

LLD's --hash-style option doesn't appear to have a "none" option or I'd 
just be making use of that here.
