src.opts.mk includes bsd.own.mk. This in turn defines CTFCONVERT_CMD depending on the MK_CTF value. We then set MK_CTF to no, which has no real effect. The solution is to set all the MK_foo values before including src.opts.mk. This should stop the cdboot binary from exploding in size for releases built WITH_CTF=yes in src.conf. Sponsored by: Netflix
