Hm, I have a vague recollection that arch/x86/boot/compressed/head_64.S
may also have been broken by PR18303.

My initial testing with a GCC-compiled kernel and just 'make CC=clang
SUBDIRS=arch/x86/boot bzImage' didn't show that up, but later testing
actually included the compressed/ directory, and did hit it.

The PR18303 fixes were merged around 2014-01-28 (r200345-r200351)
