I've found I get the best results by modifying bsd.lib.mk such that it
skips the @${LD} -x -r ${.TARGET bit when making plain .o targets.
Without this all local symbols are stripped which makes tracing into
libraries less useful.  I don't bother with debugging versions of
shared or profiled libs.

While I was at it I made the default CFLAGS in sys.mk

CFLAGS=            -O2 ${PIPE} ${DBG}

and I just add DBG=-g when compiling libs.
