When building up the command-line for the DTrace ctfmerge and ctfconvert

Browse Source 
utilities, add the ${DEBUG} variable from the kernel config.  Otherwise,
if we build a kernel with WITH_CTF=1 set, ctfmerge will not have
the -g flag set.  In this case, the cc has -g specified, so the
.o files will have debug information generated, but since ctfmerge
does not have -g set, it will strip out the ELF sections containing
the DWARF debugging info, leading to a kernel without debugging symbols.
