I mean for all platforms. I don't see any point in the build wasting 
time on zipping up the debug symbols which also makes them unusable. If 
someone cries out we could leave the feature in, but I would much rather 
not. Note that the bundle target has to unzip them again to put them in 
the symbols bundle, which is the final deliverable of the symbols.

Historically there have been various reasons for this zipping internally 
to Oracle, but I don't think any of those reasons hold up anymore in our 
current JDK 10 infrastructure.
