ELF support in sparc bootblocks.

Loadfile is from alpha, but heaviliy hacked here.
The build is done by building elf versions of boot and bootxx, then
merging the .rodata and .text sections into .text with a horrible hack
and then using objcopy to convert that into a.out.

Maybe someone will want to fix installboot to deal with ELF instead, but
I won't be that someone in the nearest future.
