That will, mistakenly, turn off optimization. I've always used separate
DBG and OPTIM values, as in the following patch, just to keep things
separate.
(Note that COPTS is _not_ supported by /usr/share/sys/sys.mk)
This patch also fixes some of the support for LDSTATIC to make it
actually work properly (the rest in some more patches below).
(I still look forward to trying the MKDEBUG and MKDEBUGLIB features.
For now I still build with DBG=3D-g OPTIM=3D-O2 and then do a separate "make
install" run with STRIPFLAG=3D'-sS "-g"' to a separate DESTDIR and then I
make a release from that and just keep the debug binaries on my build
systems. However having separate /usr/libdata/debug files that I can
install on any host would be much better.)
