x86, relocs: Refactor the relocs tool to merge 32- and 64-bit ELF
Refactor the relocs tool so that the same tool can handle 32- and 64-bit ELF. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Cc: Kees Cook <keescook@chromium.org> Link: http://lkml.kernel.org/r/1365797627-20874-5-git-send-email-keescook@chromium.org
