>Description:

We are lacking a build option like MKKDEBUG for kernel modules. Something
like MKKMODDEBUG (better names welcome) that causes all $mod.kmod to have
a corresponding $mod.kmod.gdb file in the object directory.

>How-To-Repeat:

Read src/share/mk/bsd.README and look for module debug info.

>Fix:
n/a

 I like the name MKMODDEBUG (only 1 K)

 If we're going to build the debug modules, we probably also ought to
 include them in the debug.tgz distribution set.
