the motivation for these changes is that I want to be able to add something
to LDFLAGS in /etc/src.conf and have that actually affect every executable
and shared library that is built.

we don't actually care about beep or trim, I just noticed that they were
not getting the LDFLAGS from src.conf and thought I would fix them
for completeness.  adding the include of src.opts.mk seemed to fix that.
also, a great many makefiles include src.opts.mk as the first thing and
I thought that was just some boilerplate that was expected to be done
everywhere and had been overlooked in these two.

at that point I had not changed the usage of LDFLAGS in these two makefiles.
then as I was arranging this stuff to commit, I grep'ed for other makefiles
that assign rather than append to LDFLAGS (like I had found in bsnmpd)
and found that these same two makefiles also incorrectly assigned to LDFLAGS,
so then I added the other changes you see in those two commits.

I'm not sure why I thought that including src.opts.mk without changing
the LDFLAGS usage made things work initially.  I tried that again just now
and indeed it doesn't help, and the parts that remove the assignment to LDFLAGS
are enough.  maybe I had something stale in my obj dir before?

anyway, I'd be happy to remove the include of src.opts.mk from these again
if you'd like.
