[PATCH,resend] sparc64: build compressed image (zImage) by default

Subject: sparc64: build compressed image (zImage) by default

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.

Jurij. I added his Signed-off-by with his permission.

The patch was tested to work during my recent tests for the cmd64x issue.
