code review request for minor FDS tweak (7157296, 7158067)

[Daniel D. Daugherty]

Greetings,

In my recent Full Debug Symbols changes, I added the new
ENABLE_FULL_DEBUG_SYMBOLS build flag. I originally implemented
this flag to disable debug info for all build configs which
doesn't make a whole lot of sense for non-product builds. After all
what's a debug build without debug info? (Pretty much the same
thing as a product build).

As is usual, I have one bug to track the hotspot repo changes and
another bug to track the other repos:

     7157296 3/4 FDS: ENABLE_FULL_DEBUG_SYMBOLS flag should only affect
                 OPT builds
     7158067 4/4 FDS: ENABLE_FULL_DEBUG_SYMBOLS flag should only affect
                 product builds

Thanks, in advance, for any review comments.
