The best way to build something with debugging support is to set
DEBUG_FLAGS in the environment (or make.conf):
# cd /usr/src/lib/libedit
# make cleandir
# make cleandir
# make obj
# env DEBUG_FLAGS='-g' make all install
Setting DEBUG_FLAGS adds the value of DEBUG_FLAGS to any existing CFLAGS
and disables symbol stripping, all at the same time. Look at bsd.lib.mk
under /usr/share/mk for the way DEBUG_FLAGS works.
