When this knob is set standalone debug files for shared objects are

The -g flag is automatically added to CFLAGS if debug files are enabled
(but the shared objects are still installed stripped, if DEBUG_FLAGS is
not set).

This is a refinement of my earlier change for shared object standalone
debug. This patch also includes the following changes:
- Change GDB's standalone debug file path to the default /usr/lib/debug.
- Change debug file extension from 'symbols' to 'debug', in line with
GDB's documentation. I initially followed the kernel build example
in choosing .symbols, but .debug more accurately represents the use
of these files.
This looks promising. After this patch, running "gdb
./a.linked.with.libc.so.out" should work without any extra thinking?
I'll give it a shot.
We should enable this flag by default. A big FreeBSD strength is our
debugging system.
