FDS stands for Full Debug Symbols and is defined that way in
quite a few Makefiles... We just call it FDS for short...

Whatever we do here has be architecturallyconsistent across the
various OpenJDK platforms. The above settings would not work well
on non-Linux platforms so I'm not in favor of doing that.

However, I don't have a problem with providing support for config'ing
a build to work with the downstream Linux repos...

When I did the Full Debug Symbols (FDS) project, I made it architecturally
consistent  between the HotSpot and JDK sides. Since the new build system
has arrived, something of the consistency has been broken and I haven't
been back on the JDK side to see what happened...
