Indeed - disabling that on all kernels gives:

615M    /hosts/evbarm
9.7G    /usr/obj/evbarm
2.2G    /usr/obj/evbarm/usr/src/releasedir
3.7G    /usr/obj/evbarm/usr/src/sys/arch/evbarm

I like that, and we could add build.sh kernel.gdb=MYKERNEL

Or, like matthew suggested, control it by something in /etc/mk.conf, with
default to "no -g".

This may need further discussion, but as a immediate step I would like
to manually override all DEBUG=-g for *_INSTALL kernels, which probably
is already enough to get the builds going for now.

Anyone see problems with that?
