Trouble Cross-compiling for hpcarm (seems related to lang/gcc2)

Howdy.

I currently have three NetBSD/hpcarm systems stuck on NetBSD 6.1 due to the lack of binary packages in pkgsrc. I'd love to move them over to 7.0.1. I am trying to build hpcarm binaries under NetBSD-7.0.1/amd64 and I've run into the same trouble as outlined at the bottom of this page by Silas Cou: http://www.silas.net.br/tech/pkgsrc/pkgsrc-troubleshooting.html

This is on a fresh install of NetBSD/amd64. I unpacked pkgsrc from inside the installer, then followed the instructions outlined here: ftp://ftp.netbsd.org/pub/pkgsrc/current/pkgsrc/doc/HOWTO-use-crosscompile

While doing "make package" on /usr/pkgsrc/cross/libtool-base,

The above error seems to be related to "NOT_FOR_PLATFORM+=NetBSD-[6789]*-*" in the lang/gcc2 Makefile. Commenting that line out is probably not the right thing to do, but in case it is, that's yielding a whole other set of errors, ultimately transpiring from the fact that arm--netbsdelf-gcc doesn't exist while trying to build lang/gcc2.

mk.conf is as follows (comments stripped for brevity)

USE_CROSS_COMPILE?= yes
CROSSBASE= ${LOCALBASE}/cross-${TARGET_ARCH:U${MACHINE_ARCH}}
.if !empty(USE_CROSS_COMPILE:M[yY][eE][sS])
MACHINE=hpcarm
MACHINE_ARCH= arm
TOOLDIR= /usr/obj/tooldir.NetBSD-7.0.1-amd64
CROSS_DESTDIR= /usr/obj/destdir.hpcarm
PACKAGES=${PKGSRCDIR}/packages.${MACHINE_ARCH}
WRKDIR_BASENAME= work.${MACHINE_ARCH}
.endif

I'm an admitted newbie to cross-compiling, but I'm beginning to think this is why there aren't any binary packages for NetBSD7/hpcarm yet...

Advice?
