 Triggering this off COPTS is dangerous, it conflicts with:
 
 makeoptions     COPTS="-O2 -fno-omit-frame-pointer"
 
 in the amd64 GENERIC config.
 
 One could argue that -fno-omit-frame-pointer should go into CPUFLAGS
 instead and -O2 into DEFCOPTS.
 
 But maybe you should just set CONFIGOPTS="-D DEBUG=-g" ?
