Rename ELF_LIB_OBJS to LIBELF_OBJS as to have the same name as in
libs/guest/.
Replace "-I" by "-iquote".
Remove the use of "vpath". It will not works when we will convert this
makefile to subdirmk. Instead, we create symlinks to the source files.
Since we are creating a new .gitignore for the links, also move the
existing entry to it.
