I don't think it's a good idea to add elf.h or elf.h-like headers to
newlib at all. Newlib is often used within the same source tree as BFD,
binutils, GCC and GDB. Part of these source trees is the GNU elf.h file
in the include subdir, parallel to the newlib subdir. So the stuff is
usually already available. Apart from the fact that elf.h doesn't match
the job description of a C library well, it would be a duplication of
already available information. This would not only lead to confusion,
it would also require to maintain the same information in two places.
