coreutils 8.4 and 7.5 and bash all give me the same result for the
commandline being run. This was just one of the things I tried and it
didn't fix the problem.

Here is what is run from the buildlog...
  (cat arch/x86/boot/compressed/vmlinux.bin | lzma -9 && printf
\\150\\111\\241\\007) > arch/x86/boot/compressed/vmlinux.bin.lzma || (rm
-f arch/x86/boot/compressed/vmlinux.bin.lzma ; false)

I tested printf out...
# printf \\150\\111\\241\\007 | xxd
0000000: 6849 a107                                hI..

coreutils 7.5
# /usr/bin/printf \\150\\111\\241\\007 | xxd
0000000: 6849 a107                                hI..

coreutils 8.4
# /usr/bin/printf \\150\\111\\241\\007 | xxd
0000000: 6849 a107                                hI..


That confirms it? its not the b0rked printf issue afaics :)
