this patch adds tftpboot.img as a target when building sparc64 kernels.
This is used for net booting sparc machines.
Since it contains some (minor) changes to common code, I am putting out
on this list. The sparc arch specific stuff will be in my updated
sparc64 kbuild patch.

+ tftpboot.img This is the vmlinux file converted to a.out format
+ so that it can be booted over a network using tftp

Note that bzImage format does NOT use the `bzip' or `bzip2' compression
programs, as some have suggested.
