Symbols aren't very useful unless they are full debugging symbols, but
with full debugging symbols the unstripped binaries would be _very_ large.
With only non-debugging symbols, the symbols' size in most shared
executables is small since most symbols are in libraries. However,
all libraries may need to be compiled with full symbols irrespective
of the default policy for stripping installed binaries, so that you
can debug [non-installed] binaries.

The case of full debugging symbols is already handled here. I believe
some committers (not bde) actually use it. Similarly in bsd.prog.mk.
So is the case of not stripping installed binaries (STRIP=).
I don't want the bloat from building and/or installing libraries with
full symbols, but miss an easy way to build them when needed (maybe on
demand -- libc now takes only a few seconds to compile). If you fix
this, don't forget the case of libraries in ports bloatware that takes
more than a few seconds to compile :-).
