missing bits in elf.h

[Jeff Johnson]

Trying to build kompozer again to exercise the new nss/nspr things and I'm
falling down on elf.h:

Chatted with Mats on IRC, and it looks like these would be safe to add:

09:07 < mwichmann> the elf things look like mistakes on our part, not so odd...
                   now we're using our own elf.h
09:07 < mwichmann> ELF32_R_TYPE is a macro for extracting info, not anything
                   new in elf, so safe
09:08 < stewb> it's supposed to detect the 4arg vs 5 arg versions and adapt,
               but failing,even when I try to force the necessary defines
09:08 < mwichmann> the EM stuff we should have, /* Legal values for e_machine
                   (architecture). */
09:08 < mwichmann> those have ALWAYS been part of the low-level-abi description
09:09 < stewb> shall I bug it?
09:09 < mwichmann> yes, please, the 386 relocs also look like they have no
                   reason to be excluded
09:09 < mwichmann> we must not have pursued this since we got "our own elf.h"
