Re: Buildkernel fails in /usr/obj/usr/src/arm.armv7/sys/GENERIC/vchiq_shim.o

hi!

There's obviously something wrong with my cross building, because when I
try cross building armv7 on my laptop it succeeds

Anyone have any ideas what I'm doing wrong here? thanks!

```
#!/bin/sh

OBJ_BASE="/home/adrian/work/freebsd/head/freebsd-obj-arm"
SRC_BASE="/home/adrian/work/freebsd/head/freebsd-src-arm"
PORTS_BASE="/home/adrian/work/freebsd/head/freebsd-ports-arm"
MAKE_FLAGS="-j8 -s"
X_TARGET_ARCH="armv7"
KERN_CONFIG="GENERIC"
BUILD_FLAGS="NO_CLEAN=1"

env MAKEOBJDIRPREFIX="${OBJ_BASE}" make ${MAKE_FLAGS} buildkernel
KERNCONF=${KERN_CONFIG} ${BUILD_FLAGS} TARGET_ARCH=${X_TARGET_ARCH}
```
