These were all helpful to me for debugging= , I think you just want -g though

Hi, everyone. I just learned how to develop module= s in FreeBSD.
A simple= one with this Makefile
```
KMOD=3D hello
SRCS=3D hello.c
<= div>
.include <bsd.kmod.mk>
<= div class=3D"gmail-protonmail_signature_block-proton">```
Type `make` and it works. But no d= ebug symbols by default.

Th= ere are variables in `sys/conf/kmod.mk<= /span>` which control the compiling process. But I did not find anyone that c= an help to add debug symbols.

Thanks.
