      kbuild: really fix bzImage build with non-bash sh · 1373411a
      Jonathan Nieder authored
      In an x86 build with CONFIG_KERNEL_LZMA enabled and dash as sh,
      arch/x86/boot/compressed/vmlinux.bin.lzma ends with
      '\xf0\x7d\x39\x00' (16 bytes) instead of the 4 bytes intended and
      the resulting vmlinuz fails to boot.  This improves on the
      previous behavior, in which the file contained the characters
      '-ne ' as well, but not by much.
      
      Previous commits replaced "echo -ne" first with "/bin/echo -ne",
      then "printf" in the hope of improving portability, but none of
      these commands is guaranteed to support hexadecimal escapes on
      POSIX systems.  So use the shell to convert from hexadecimal to
      octal.
      
      With this change, an LZMA-compressed kernel built with dash as sh
      boots correctly again.
