x86, amd: Include linux/elf.h since we use stuff from asm/elf.h

After merging the moduleh tree, today's linux-next build (x86_64
allmodconfig) failed like this:

  arch/x86/kernel/sys_x86_64.c:28:10: warning: 'enum align_flags' declared inside parameter list
  arch/x86/kernel/sys_x86_64.c:28:10: warning: its scope is only this definition or declaration, which is probably not what you
  want arch/x86/kernel/sys_x86_64.c:28:22: error: parameter 3 ('flags') has incomplete type
  [...]

Presumably caused by the module.h split interacting with a
new commit dfb09f9b7ab0 ("x86, amd: Avoid cache aliasing penalties
on AMD family 15h") from the x8 tree.
