My impression always was that elf.h is essentially a C language
rendition of various Elf standards (sans algorithms).
What prompted me to post this patch in particular was that GCL folks
seem to be in a need of those defines . I'm not in contact with them
personally, this issue was brought to my attention via Fedora ARM list.
I offered composing a patch as it seemed an obvious omission.

OK, I'll prepare a patch with comments.
