Images target failes when configured with --disable-zip-debug-info

gmake[2]: *** No rule to make target
`/path/to/jdk8/workspace/build/linux-x86_64-normal-server-slowdebug/images/_strip_jre/bin/jarsigner.debuginfo.stripped',
needed by `jre-image'. Stop.
gmake[2]: *** Waiting for unfinished jobs....
gmake[1]: *** [images] Error 2
make: *** [images-only] Error 2

This is caused by a find expression for executables picking up .debuginfo files. Normally these are zipped into .diz files that aren't picked up.
