Latest results from x86-64 and aarch64:

Both are little endian.  The only difference is for x86-64, I'm off of
commit 750eaa47f10f ("x86: Check plt_got before using .plt.got") and
for aarch64 I'm off of ee7e95efb981 ("merge_gnu_build_notes reloc
deletion").  I don't think that should matter.

I've also got a small incremental to fix some trailing whitespace, and
s/SPARC/BPF/ in one file, attached.
