netbsd-7 DRMKMS in release build impossibly large?

["John D. Baker" <jdbaker%mylinuxisp.com@localhost>]

Recently, patches were applied to the netbsd-7 branch to build the DRMKMS
kernel as part of the regular i386/amd64 release build and offer it as
an option in 'sysinst'.

  http://mail-index.netbsd.org/source-changes/2014/12/04/msg061139.html

The resulting kernel weighs in at 100+MB rather than ~18MB when built
using the "kernel=DRMKMS" target of 'build.sh'.  The 'gzip'ped kernel
is ~42MB instead of ~7MB.

Also, I noticed the following:

--- kern-DRMKMS ---
cd /r0/nbsd/netbsd-7/src/sys/arch/amd64/conf && /r0/build/netbsd-7/tools/amd64/bin/nbconfig -s /r0/nbsd/netbsd-7/src/sys  -U DEBUG -b /r0/build/netbsd-7/obj/amd64/sys/arch/amd64/compile/DRMKMS DRMKMS

I never saw a final link message for "kern-DRMKMS".
