808e5c4ba0 Fixes to Kbuild to build on ARM architecture.
This commit fixes issues to allow build on ARM architecture.
- It fixes the include paths in Makefiles.
- It fixes the include path for the offsets.c compilation.
- It fixes the linker command. This changes is needed because gcc
  ARM cross-compiler does not accept an AT() command without
  specifing an address explicitly. This corner case appears
  on ARM architectures when XIP is disabled.

This commit deletes references to Documentation directories for

Also, This commit deletes the reference to sample directory for

Finally, this commit temporary fixes the references to assembly
files .s extensions. This has been marked as a BUG until all .s
files can be renamed to .S files.
