This is only for LEON as u-boot for SPARC only supports LEON.

Now that we use the same piggyback for 32 and 64 bit
we can drop the _32 suffix.
Include some trivial unification in the Makefile
now that 32 and 64 bit can share the same piggyback command.

piggyback_32 adapted to support sparc64:
- locating "HdrS" differs for sparc and sparc64
- sparc64 updates a_text, a_data + a_bss in the final a.out header
Updated Makefile to use piggyback_32 for sparc64.
Deleted the now unused piggyback_64.c
piggyback_32.c is host endian neutral and works on both
little-endian and big-endian hosts.
This fixes a long standing bug where sparc64 could not
generate tftpboot.img on a x86 host.

As we always convert to a.out there is no need to
support ELF.
Removing ELF support because:
- it is not used
- it simplifies code to support a.out only

Besides creating the uncompressed vmlinux image for sparc64, also
create a compressed zImage. This is more consistent with other
architectures and required to make the 'deb-pkg' target work.

The tftpboot build was failing with missing file errors.
It turns out that $(obj)/image wasn't being generated which was causing the a.out conversion to be skipped and hence piggyback to be called with nonexistent files.

Kjetil Oftedal mentioned that piggyback_32 was failing
when building a sparc image.
I tracked this down to the fact that the kernel no longer
provided an absolute symbol named "end".
Commit 86ed40bd6f ("sparc: unify sections.h")
renamed end to _end but failed to update piggyback_32.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
