Don't send: MAKEALL: Display MD5SUM

 === Do not send to ML, Do not merge into the mailline ===

 What is this ?
 --------------

When you change some makefiles and you want to confirm
your changes are harmless, this patch will be helpful.

With this patch, MAKEALL will display md5sum of
 -  ./u-boot.bin
 -  spl/u-boot-spl.bin (if it exists)
 -  tpl/u-boot-tpl.bin (if it exists)
 -  examples/standalone/hello_world.bin (if it exists)

If the same md5sum is displayed, it means your commits
still generate the same outputs.

Timestamp and version information must be disabled,
otherwise MAKEALL will show the different md5sum at every build.
